One more... how do they do that??
I understand how these things work. What I wonder about is the design process - I could not design anything even remotely this clever.

                                        These are made using a 3d printer and an animated 3d virtual model. The turn table is lit using an LED strobe lamp (some have been able to tweak the digital camera sweep to stop the motion instead)
here is another similar application:
@Lukian by hecky thump. Tha's clever.
This is so neat!

                                        I posted this and another one. I had to read up to see how they work. Pretty cool.
