Amazing LEGO Mindstorm 20 modules

Lego Mindstorms is a line of programmable robotics/construction toys, manufactured by the Lego Group. It comes in a kit containing many pieces including sensors and cables. This guy used 20 GBC modules built by him, 4 modules(screw,sweeper,shovel,pump) based on Philo's. The module at 5:24 based on Isogawa's and the pneumatic module at 7:00 using Linmix's image. Some other modules were inspired by GBC fan's.

I liked the fact that at 2:33 the module is sorting the balls by color. Too bad they are mixed together after that. I was hoping for something more.
