Design-a-Week project late. So this week's is early.
This one is a simple concept with complicated geometry. I wanted to make the classic Ferris Wheel into something more 3-dimensional.
At IAAPA, I saw a company using a fixed wheel with a tank track-like belt moving the cars around it. I figured with something similar, the wheel could make turns around a more complicated shape (a sphere instead of a wheel, in this case). In my model, the 56 ball-shaped cars will swing but they stay upright by gravity and 2 axes of passive swivel.
I've mocked up 4 versions of this: basic structure, simple colors, "Atomic Sphere" and "Planet X". You can see some still shots of all 4 models HERE. And there are some short animations of each there too.
