Bike to a greener world?

Is this not the best idea ever?

The bubbles trail behind your bicycle and land along the edges of the sidewalk where they will eventually blossom into wonderful green flowers and plants.

It's all the workings of a WiiMote packed inside of a spraypaint can. He hopes to create a communal, online spray paint community for people to create their own personal tags and share them with the rest of the world.
