Blue & Cute. Amazingly the tires actually turn freely on the hubs allowing it to actually roll. That was more of a pleasant surprise than an intended part of the design ;)
It has a compact design, but it turns out to be pretty complicated when I see it up close, so you probably spent a lot of time working on it. I think it turned out nicely. If you had the pieces, you could probably build more of them in different colors.
