Have you seen this fractal?
Unknown fractal. It's sort of like a Sierpinski gasket but with circles. (via migurski)
Vol Libre, an amazing CG film from 1980
In 1980, Boeing employee Loren Carpenter presented a film called Vol Libre at the SIGGRAPH computer graphics conference. It was the world's first film using fractals to generate the graphics. Even now it's impressive to watch:
That must have been absolutely mindblowing in 1980. The audience went nuts and Carpenter, the Boeing engineer from out of nowhere, was offered a job at Lucasfilm on the spot. He accepted immediately. This account comes from Droidmaker, a fascinating-looking book about George Lucas, Lucasfilm, and Pixar:
Fournier gave his talk on fractal math, and Loren gave his talk on all the different algorithms there were for generating fractals, and how some were better than others for making lightning bolts or boundaries. "All pretty technical stuff," recalled Carpenter. "Then I showed the film."
He stood before the thousand engineers crammed into the conference hall, all of whom had seen the image on the cover of the conference proceedings, many of whom had a hunch something cool was going to happen. He introduced his little film that would demonstrate that these algorithms were real. The hall darkened. And the Beatles began.
Vol Libre soared over rocky mountains with snowy peaks, banking and diving like a glider. It was utterly realistic, certainly more so than anything ever before created by a computer. After a minute there was a small interlude demonstrating some surrealistic floating objects, spheres with lightning bolts electrifying their insides. And then it ended with a climatic zooming flight through the landscape, finally coming to rest on a tiny teapot, Martin Newell's infamous creation, sitting on the mountainside.
The audience erupted. The entire hall was on their feet and hollering. They wanted to see it again. "There had never been anything like it," recalled Ed Catmull. Loren was beaming.
"There was strategy in this," said Loren, "because I knew that Ed and Alvy were going to be in the front row of the room when I was giving this talk." Everyone at Siggraph knew about Ed and Alvy and the aggregation at Lucasfilm. They were already rock stars. Ed and Alvy walked up to Loren Carpenter after the film and asked if he could start in October.
Carpenter's fractal technique was used by the computer graphics department at ILM (a subsidiary of Lucasfilm) for their first feature film sequence and the first film sequence to be completely computer generated: the Genesis effect in Star Trek II: The Wrath of Khan. The sequence was intended to act as a commerical of sorts for the computer graphics group, aimed at an audience outside the company and for George Lucas himself. Lucas, it seems, wasn't up to speed on what the ILM CG people were capable of. Again, from Droidmaker:
It was important to Alvy that the effects support the story, and not eclipse it. "No gratuitous 3-D graphics," he told the team in their first production meeting. "This is our chance to tell George Lucas what it is we do."
The commercial worked on Lucas but a few years later, the computer graphics group at ILM was sold by Lucas to Steve Jobs for $5 million and became Pixar. Loren Carpenter is still at Pixar today; he's the company's Chief Scientist. (via binary bonsai)
Fractal universe
Is the universe fractal-like, even on large scales? A group of Italian and Russian scientists argue that it displays a fractal pattern on a scale of 100 million light years. Other scientists aren't so sure.
Many cosmologists find fault with their analysis, largely because a fractal matter distribution out to such huge scales undermines the standard model of cosmology. According to the accepted story of cosmic evolution, there simply hasn't been enough time since the big bang nearly 14 billion years ago for gravity to build up such large structures.

Benoit Mandelbrot and Paola Antonelli talk about, among other things, fractals, self-similarity in architecture, algorithms that could specify the creation of entire cities, visual mathematics, and generalists.
This has been for me an extraordinary pleasure because it means a certain misuse of Euclid is dead. Now, of course, I think that Euclid is marvelous, he produced one of the masterpieces of the human mind. But it was not meant to be used as a textbook by millions of students century after century. It was meant for a very small community of mathematicians who were describing their works to one another. It's a very complicated, very interesting book which I admire greatly. But to force beginners into a mathematics in this particular style was a decision taken by teachers and forced upon society. I don't feel that Euclid is the way to start learning mathematics. Learning mathematics should begin by learning the geometry of mountains, of humans. In a certain sense, the geometry of...well, of Mother Nature, and also of buildings, of great architecture.

Hmm, perhaps Richard Taylor's fractal analysis of Jackson Pollock paintings isn't that useful after all.

Is this mess of a painting bought at a thrift shop for $5 a Jackson Pollock worth $50 million? I wonder if Richard Taylor has been contacted to examine the painting.
