AirTrax- Reinventing the Wheel
 

I've known of these for a long time, but someone reminded me of it the other day.

These are the coolest wheels ever- Airtrax. They allow any direction of movement. There coolest product is the Sidewinder. That page includes a really cool video of a lift loader using the omni-directional wheel system. More of their videos can be found here.

Those are sweet Ive seen them on a wheel chair.

wow....we need these on cars for parking...xoxoxoo

That is cool! I love it when someone finds an overlooked simple idea and makes it work.
