Oh, it's made of bread and the wheels are cookies!

Well, they are going faster, as they are smaller wheels and need more turns to give the same distance ;)
But it might seem that they are going extra fast because they only consist of two different frames.. maybe I shouln't have done the 'spokes' as a cross, but something asymmetric instead.

Thank you :)

it kindof looks like the front wheels are going faster than the back wheels, its still really good though

Hmm, I think you're right. At least the wheels could go a little faster, but I'm afraid the smoke will look funny if I speed that up as well. I'll go mess around with it some more :D Thanks!

 Not bad, could be better if you sped up the animation a little.
