pInnovative uploader Simon got an idea from his good friend Henrik – build something new for the 30-year anniversary of Back to the Future. Using Omni-Directional wheels, Simon was able to create a skateboard out of Lego that doubles as a hoverboard. The prototype uses 8 NXTs, 16 NXT motors and 8 Rotacaster wheels. What you can’t see is Simon’s second attempt to ride it after the camera was turned off.
