if you van made this in a kinda wheel/car and less big file, maybe the others will rate it higher

I have to agree with ianno, this is a neat little proof of concept, very original, and I like it. But, it would be much better to see this used in some sort of context, get peoples imaginations going as to what this could be used for, I don't have any suggestions myself, but this scene feels a bit unfinished and it's a shame.
On that basis I'm going to give it an 8/10, otherwise, good work.

And yeah the filesize is a bit on the large side for something so small (It still downloaded in like less than 5 seconds for me) but I don't think it should be rated down for this.

Very interesting wheel desigh!! VERY GOOD!
You should add it too a car (car can be very simple) and show the power of it, one problum is that it bounces quite a bit when u start it, i think the weaight of the "car" will solve that if u actely make a car for thoes wheels.
