Everyone loves it when grown-ups get crazy with the Lego. Constructing a pneumatic wheel out of it, as Philippe Hurbain has done, is only the latest example of a process that can only end when the entire universe is modeled with chunky styrene blocks.
The wheel is hexagonal, but overcomes its hexagonality through the power of six pressurized pistons, which blast it along at a disturbing clip. Another way to terrify your pets, courtesy of amateur robotics.
