The eyeballing game

posted by Jason Kottke   Oct 16, 2008

The eyeballing game tests how good you are at lining things up. I got a 4.46 on my first try, but my hand slipped on one of them so I’m going to try again… Leave your best (or worst) score in the comments. (via core77)

Update: 4.34. I suck at parallelograms and triangle centers.

Reader comments

Mike RundleOct 16, 2008 at 10:35AM

3.3 average… got a couple 0s but then a 14.7 miss that raised the average. Ouch!

IvyOct 16, 2008 at 10:36AM

16.97. I have a type of dyslexia that makes this impossible for me to do. I have no visual/depth perception skills at all. I would read a book in the corner and refuse to to Tanograms in Kindergarten.

SeanOct 16, 2008 at 10:39AM

i suck at parallelograms and convergence

Jim BiancoloOct 16, 2008 at 10:40AM

2.10. Convergence gives me the most trouble.

dennis gOct 16, 2008 at 10:41AM

2.33. I wonder if there is any correlation to the supposed right and left hand side of the brain thinkers.

ChrisOct 16, 2008 at 10:43AM

2.37. I blew the final Convergence test.

Just out of curiosity: What were your childhood/grade school interests? I’m interested to see if there’s a correlation between the scores on this test and an interest in engineering or technical drawing…

SeanOct 16, 2008 at 10:45AM

2.66
left-handed (although using right-hand with mouse)
math and science interests, though not engineering or tech-drawing

GrantOct 16, 2008 at 10:45AM

I was doing good on my first one, until some sort of bug on Convergence gave me a score of “15385924.19 (lower is better)”.

My second try was a more reasonable 1.90.

NicholeOct 16, 2008 at 10:48AM

3.22
I did pretty well on convergences and right angles.

Steve IvyOct 16, 2008 at 10:49AM

2.86 - I rock bisecting angles, parallelograms rock me.

MichelleOct 16, 2008 at 10:52AM

5.27, including a hand slip that stuck me with a 38.2 on a triangle center. Manually calculating that out gives 3.62. I had one more big outlier, a 14, that I can’t explain away with a hand slip, but if I calculate it out too, that’s a 2.55.

So I played again, thinking to really put some effort in this time and get the score I “should’ve” gotten the first time.

I got a 5.52.

ErikOct 16, 2008 at 10:54AM

3.70 is my best after 3 tries.

Dang center of triangles - I hate that one.

Mike RundleOct 16, 2008 at 10:57AM

Erik, yup, the center of the triangle one is what messed me up as well.

MollyOct 16, 2008 at 10:57AM

5.62. My first parallelogram screwed me because I didn’t quite get what was going on and missed the mark by 32. Otherwise, fairly good.

jkottkeOct 16, 2008 at 10:59AM

I’m having trouble with the mouse pointer getting in the way…I wish it disappeared while dragging.

I’m also a lefty who mouses righty. I’ve never been that keen on drawing or engineering. Design was always a struggle for me, lots of trial and error and never effortless. Probably explains why I’m smack in the middle of the eyeballing distribution.

EthanOct 16, 2008 at 11:01AM

3.10
Convergence=easiest. Centers = hardest, including bisecting the angle.

I was going to be an engineer or architect but changed my mind. Lots of math and lots of doodling.

CatherineOct 16, 2008 at 11:02AM

I think I’d score way lower if I moused lefty (as a lefty), but as it is, I’m a 4.77 and totally crap with the convergence and triangle centres.

BenOct 16, 2008 at 11:04AM

What threw me off at first on the triangle one was mistakenly interpreting it as “equidistant from vertices” rather than “equidistant from edges”. Makes a huge difference.

Tom DolanOct 16, 2008 at 11:04AM

2.21 — first try, should be able to get it a lot better.

benOct 16, 2008 at 11:05AM

Ryan SholinOct 16, 2008 at 11:07AM

3.89

I bent the convergence line on the first attempt, which netted me a 20 to throw everything off.

JasonOct 16, 2008 at 11:12AM

2.75; parallelograms ARE the hardest part.

AmyOct 16, 2008 at 11:13AM

3.79. Apparently I am no good at bisecting angles.

ArminOct 16, 2008 at 11:15AM

3.68
Hit all three center-circles at 0.0! But the parallelograms and triangle centers screwed me up.

Tom DolanOct 16, 2008 at 11:19AM

Actually, I’m getting worse! Three scores under 3 but getting under 2 is really tough.

marc CardwellOct 16, 2008 at 11:22AM

3.61, this was fun. on one parallelogram, i got a 0, on another a 12.
i’m sending this to the art people at my office/

MeganOct 16, 2008 at 11:26AM

2.62 is my lowest of 4 games. I’m trying to get my husband to play, he’s a landscape architect, and after all his time using AutoCAD I think he would be good at it.

KhrysOct 16, 2008 at 11:26AM

2.24. Triangle center was tough.

SaraOct 16, 2008 at 11:27AM

2.21, on the parallelogram. Bisecting the angles was evil, I got a 111.1! :(

BobOct 16, 2008 at 11:31AM

3.85 best. I can bisect the crap out of angles. But I can’t make right angles… this should probably scuttle my woodworking plans.

David WertheimerOct 16, 2008 at 11:32AM

3.6 on my first time all the way through. The range is more interesting to me than the average… I had a 0.2 but also an 8.5.

Tip: try yanking the positioner away from its starting position, toward the black lines, then slowly repositioning it into the ideal. I find it’s far less distracting to start from nothing.

jkottkeOct 16, 2008 at 11:33AM

I’m thinking of turning the comments off because YOU’RE ALL SO MUCH BETTER THAN ME! BASTARDS!

Uros MilicevOct 16, 2008 at 11:34AM

hardest part is equidistant point in triangle….really nice test….

Neill HarmerOct 16, 2008 at 11:36AM

3.61. Would have been way lower had I not TOTALLY screwed up on the intersecting points. oh well. this was the best ive gotten so far.

Matt VOct 16, 2008 at 11:38AM

2.86 - I have a long history of being able to notice off-by-1-pixel errors.

harryhOct 16, 2008 at 11:39AM

3.83 with a big boost when I got 0.0 on the right angle

JenniOct 16, 2008 at 11:40AM

8.66, I forgot what a parallelogram was at first..oops

ChrisOct 16, 2008 at 11:41AM

8.07 - and I thought I had done great.

Bill KeaggyOct 16, 2008 at 11:41AM

3.73. Mostly b/c I screwed up the bisect angles.

owenOct 16, 2008 at 11:43AM

6.81. had a few 11s but I’m pretty good at angles. next time have moving targets!

Andrew HelmsOct 16, 2008 at 11:49AM

4.61, I also suck at parallelograms (10.8) and triangle centers (16.6).

jkottkeOct 16, 2008 at 11:52AM

3.90. F%$*#ing parallelograms.

DanOct 16, 2008 at 11:58AM

First Try: 3.08 - Midpoints were the worst for me (5.4-7.2), but bisect angles were the best (0.5-1.2). I also got a perfect 0.0 on my last right angle!

I’m a designer by trade. Hopefully that has helped me….

JoshOct 16, 2008 at 11:58AM

11.07 - I’m not sure I even understand the idea of convergence now.

sunkidOct 16, 2008 at 12:09PM

2.36 in my second attempt… blew the last and third to last ones

Mathew IngramOct 16, 2008 at 12:15PM

2.32

JenniferOct 16, 2008 at 12:17PM

2.41 on my first try! i did a great job at right angles (0.7, 0.3, 0.4). that was fun! i’m an engineer and have always enjoyed math and science, but i’m not sure that has a lot of bearing on how well you do. i actually think for some of the tasks (like convergent and angles), it has to do with how observant you are about the way some pixels look at certain line angles, etc…

metkere.comOct 16, 2008 at 12:19PM

4.03. I think that’s not my cup of tea.

BrandonOct 16, 2008 at 12:40PM

3.96, convergence and the equidistant point were my tough ones

metkere.comOct 16, 2008 at 12:47PM

Wow, 2.52 is my best try!

gunnarhafdalOct 16, 2008 at 12:50PM

Got 3.0, the third part screwed me up so it was higher :/

endashOct 16, 2008 at 12:57PM

2.91 … midpoints on the line were my worst, followed probably by the triangle ones. I rocked at convergence and bisecting the angle

AlaninaboxOct 16, 2008 at 12:58PM

Overall score: 3.13

Parallelogram 13.0 2.2 1.0
Midpoint 1.0 4.5 2.8
Bisect angle 7.7 0.1 1.8
Triangle center 3.8 3.7 3.7
Circle center 2.2 2.2 2.2
Right angle 2.7 2.9 0.1
Convergence 0.0 6.0 2.2

I’m not sure what happened with that first one….

MaxOct 16, 2008 at 12:58PM

2.17 - Circle center was my worst

sellkeOct 16, 2008 at 12:58PM

First (haphazard) try = 2.70. I think I now know why most designers HATE working with me. Be interesting to put a timer on the test, too.

AlaninaboxOct 16, 2008 at 1:00PM

Architect BTW.

AlaninaboxOct 16, 2008 at 1:09PM

wow what a great way to blow time at work and impress the boss at the same time…
3.01 on try # 2. I had 3 perfect 0.0’s on the midpoints.

MattOct 16, 2008 at 1:13PM

3.96 on second try. Parallelograms are a killer. I find the faster I go, the better my score is.

NormanOct 16, 2008 at 1:25PM

3.98

not as good as my OCD wants it to be, but not bad!

MOct 16, 2008 at 1:27PM

3.18 Another lefty mousing w/ right. Musician.

GloriaOct 16, 2008 at 1:32PM

2.82 2nd try. Not bad for an old lady - 61 years old! I’ll keep trying until I get in the top 10!

Bill BOct 16, 2008 at 1:37PM

2.24 (1st try)
Lefty mousing w/ right. Engineer.

NickOct 16, 2008 at 1:45PM

2.65 Designer. Like the previous poster, I wonder if that helps, or just depends on personality. I think I would suck at the color one or a music test.

Barry KellyOct 16, 2008 at 1:50PM

2.88 first go. Averages were trending down quite a bit, but don’t have the patience to do it again.

BillyOct 16, 2008 at 1:53PM

5.31

I have a strabismus (lazy eye) so my perception is generally skewed.

heatherOct 16, 2008 at 1:53PM

I did almost perfect on convergence and right angles, which I find interesting given my profession—RN in an ICU. I use a level at work to get many measurements (need to level right atrium of heart to pressure transducer) but must be able to eyeball level often in emergencies, and I need to have a good eye for angles in order to change the head of the bed angle (when I can’t see the bed angle indicator). Just thought you’d all like another persepctive than that of designer or architect…

msilverOct 16, 2008 at 1:56PM

2.61 I noticed that I was getting really good in the beginning and then I must have gotten sloppy because it dropped sharply after one or two f-ups.

judson Oct 16, 2008 at 2:05PM

I can hang a picture real straight! 5.73

AndresOct 16, 2008 at 2:35PM

2.73 I totally blew one of the midpoints. fun stuff.

Not too bad for a first try

jennyOct 16, 2008 at 3:23PM

2.61 first try.

I can converge like nobody’s business. Personally, I think my training as a professional potter gave me an unfair advantage. Always having to eyeball angles.

essOct 16, 2008 at 3:27PM

12.something with a trackpad mouse that I am not supposed to use (disc problems)
Still, it was the parallelograms that got me. No idea even after the green line came on.

Might try again later with this computer up front and a real mouse. Although it would not be possible to do better on center of circles and right angles so I think the paralleograms just got me whipped

Virginia MurdochOct 16, 2008 at 3:53PM

3.1. I’m particularly *good* at parallelograms - I got two zeroes. Yay me!

JenOct 16, 2008 at 4:20PM

The lowest I got was 0.0 by bisecting a line and the worst was 10.1 for parallelogram. Mostly I’m in the 2—5 range.

DerekOct 16, 2008 at 4:25PM

3.48…..now to try it after some wine.

CraigOct 16, 2008 at 5:01PM

3.05 busting the last convergence on my second try. More serious.
3.76 on a relatively quick first run where I finished with a 14 on the last convergence test.

Steve PilonOct 16, 2008 at 5:04PM

3.43 — had one crazy 9.2 or something, otherwise pretty consistently below 4.

RichOct 16, 2008 at 5:23PM

2.40 pretty consistently.

Triangle is my worst by far.

I’m a graphic designer for a newspaper.

Lawrence VelázquezOct 16, 2008 at 6:46PM

Scored a couple of ~7s on my very first parallelogram and midpoint tests, which brough me up to a 3.40 overall. Best of 2.00 so far.

JoshOct 16, 2008 at 8:36PM

2.08 Yeah!!!!

Bisecting, convergence and right angles are simple enough. Centering the circle is actually easy enough, but man I had to look up equidstant centering before i got it right. Geometry class was a really long time ago. This is the only math my art brain is built for.

Michael BesterOct 16, 2008 at 9:17PM

3.28.

Parallelograms and circle centers were elusive for me, but convergence and triangle centers made up for it.

Neil JanowitzOct 16, 2008 at 10:32PM

4.20 on the first attempt. Became one with convergence and right angles, but finding the center of triangles and I really didn’t hit it off too well.

Ian TimothyOct 16, 2008 at 11:46PM

4.52 …
improved with subsequent sets.

Bobby DragulescuOct 17, 2008 at 12:59AM

2.36, largely thanks to my 0.0 in bisecting a line. Years and years of freestyle (guideless) Photoshop experience have finally paid off!

JonoOct 17, 2008 at 1:01AM

2.14 so far (4th try); 3.06 first attempt. This is addictive.

I’m an architecture student and was a math major in college, so I’ve always enjoyed working with geometric relationships like this, I guess. I sucked pretty bad at the parallelograms for a while but improved after I stopped overthinking them. The triangle centers are surprisingly intuitive, and convergence is sweet because of the extra level of checkability.

laneOct 17, 2008 at 1:52AM

it’s almost 2am. must stop. eyes going bleary. 3.40. parallelograms are the work of the devil.

kimOct 17, 2008 at 2:28AM

Parallelogram 11.7 4.1 1.4
Midpoint 6.1 9.0 1.0
Bisect angle 4.1 4.4 7.1
Triangle center 3.3 6.1 6.6
Circle center 4.2 4.1 4.2
Right angle 0.6 0.8 1.8
Convergence 5.1 11.0 4.2

4.80
got the right angle down but somehow not when it’s in a parallelogram…oh, is that because there ISN’T a right angle in a parallelogram? okay with the almost consistent offness of my circle centers. as always, thank you, thank you, thank you for you, kottke.org, etc.

VincentOct 17, 2008 at 4:20AM

13.4

I’m either blind or shouldn’t be using a trackpad.

AlistairOct 17, 2008 at 7:34AM

3.38, largely due to a 15.8 on one bisection. Consistently bad at finding the midpoint, which I thought would be easiest.

Hector GarzaOct 17, 2008 at 9:43AM

3.79 I had a 10.13 at the 2nd Parallelogram that screwed up everything.


EricaOct 17, 2008 at 9:47AM

2.93 - not so bad, but I spent time as a picture framer, so had a lot of practice at right angles!

EthanOct 17, 2008 at 10:52AM

1.97, which for about 30 seconds was #1 on the top 500 games.

I got this after about five attempts. My finger actually slipped off the mouse on the final right angle so i got a +4.2 but I saved with a 0.0 on the final convergence. I find the triangle centering and midpoint to be the easiest and the right angle and parallelogram to be hardest.

DorianOct 17, 2008 at 12:47PM

4.98. Parallelograms and triangle centers kicked my butt.

littlejoOct 17, 2008 at 3:01PM

4.26 1st time
3.52 2nd time

Convergence is easy. The rest is hard, though it helps to swivel your head.

duqOct 17, 2008 at 3:17PM

1.97

lines through a mosaic of pixels that have the same stepping are either parallel or perpendicular. paying attention to this gives a big advantage — been doing this in photoshop for some time.

crosshair cursor would be for yes.

i’d like to see:

- tests distilled and grouped into fundamental skill types (congruency, symmetry, etc) and the effects of focusing on positive vs negative space (ie: for me, bisecting segments is easy, angles are hard).

- tests covering more fundamental types, if there are any (really, i think everything reduces to congruency or symmetry).

- tested strengths/weaknesses cross-analyzed with testee’s personality/thinking types and artistic tendencies.

Eric MarcoullierOct 17, 2008 at 8:11PM

4.14 — I can’t bisect angles very well.

peter hueskenOct 18, 2008 at 10:37AM

2,54 but an 8.1 and a 10 in the last row.

That top 10 is within reach !

peter hueskenOct 18, 2008 at 10:52AM

It would be fun to have a version that has a time-bonus as well
Quicker positioning results in a lower score; max positioning time 10 sec.

stringphOct 21, 2008 at 10:04AM

2.05 … after some practice. I found triangle center and parallelogram pretty hard, angles easy.

Obviously there is some random unfairness in scoring the errors in distance as the figures are sometimes larger or smaller, which leads to an intrinsically larger or smaller pixel error for the same level of skill.

The site doesn’t seem to remember my good scores…
