Your 3D effect is not quite right. For example, if you compare your rotating crosses with pnvv's rotating crosses, you will notice a marked difference. In order to get the proper rotating 3D object, you need to sandwich a large number of crosses and axles in a row, and each will rotate individually on its own axis, even though they are all rotating together. Maybe pnvv can give you some pointers to help you out.

Nice try! It just needs some work.

Thanks Xray! I wanted to try what pnvv did, so I made this as a test.

It isn't perfect, but it's a start. Also, the rotating paddlewheels got messed up because of what Xray said, as I used multiple objects rotating on roughly the same axis to generate the illusion that it was 'rotating'.
