Guest editor: Sarah Pavis  Nov 18 2012

I am in [PARtially undIscloSed location] for vacation this week so I've asked Sarah Pavis to fill in. Her Tumblr says she's "a mechanical engineer & writer living in Chicago" and when I met her briefly at XOXO in September she didn't seem like a dishonest person so I believe that she actually is those things. Sarah has also done some writing for Buzzfeed and some tweeting for herself. She's also active on Stellar, which is where I noticed that she had a good eye for whatever the hell it is I do here, an eye that spotted this video, which goes from sexy robot to terrifyingly fast insect death machine in about 45 seconds.

Anyway, welcome Sarah!
