Charles Shopsin is a New York City-raised and Brooklyn-based software developer. In his spare time, he runs the Modern Mechanix blog. OK, I admit: a forklift is not exactly standard fare for a gadgets site, but the Airtrax Sidewinder is pretty cool. It uses a set of four individually powered Mecanum wheels that allow it to move in any direction, including sideways and diagonally. I was reminded of this video by a commenter who posted another video a couple of weeks ago on my blog. It's a 1926 snowmobile kit called the Snow-Motor. It seems really agile and looks quite fetching when slung under a Chevrolet.
