With Transformers 3: Dark of The Moon around the corner, it was cool of someone to create their own transformer with a beer can.
The canbot, as its called by the inventor , tells the can to sit on a table, looking like a normal can of beer. When he pushes a button on a Nintendo Wiimote that transforms it into small transformer/robot. The beer can has three legs, each with two servos, and can shimmy around on a tabletop or roll on its side. Pretty interesting invention.
