I'm assuming that my brother-in-law is one of my 12 regular readers, so when I read about this I had to beat him to the punch in sharing it.
Courtesy of Hack A Day comes the story of a "real" transformer that has been 10 years in the making. For about $24,000 (I'd wait for the dollar to do better against the Yen, but I wouldn't be scrambling to get one) you can get this remote control car that transforms into a remote control robot.
Someday we will be able to print these things up as kits at home? For $24,000 I'd rather get a laser cutter and a 3D printer, but that is more my speed.
