The joke may be on me.
I saw that pic on the net, laughing at it and thinking what a neat photoshop job on the wheels. I posted it and the "story" as a joke.
Apparently those are real wheels since after your post I looked closer at the picture and realized there's some type of drive unit going to whatever goes around the outside of the triangular wheel.
So what the hell are those wheels? And is that rubber around the outside, kinda like tracks?
