(PS: Shake around your mouse a little bit!)
This was one of my college computer graphics projects I did with a friend. The interface isn't exactly clear, as I haven't edited it much from back then, but you can certainly click around and see some funny lines move in weird ways!
The quick summary is: use the dropdown to select a model and click load premade; you can manually rotate the model in 3d by clicking and dragging, and you can click toggle rotation to start it moving! I'll document all the settings at a later time; it's kind of a lot, but like I said, fun with weird shapes moving around!
