Customizable Stereographic Skull

Big thanks to Joe Balint for coming up with the idea to use a skull for the stereographic projection!
I modified my script to create a difference from a hollowed out skull and the projected picture, so adding a light in the correct position should display the picture. This is just a proof of concept though, it may be hard to print or find the right spot to place the light. Later it might be possible to modify this into a full-blown lamp.
I have not printed it yet, but it slices just fine in Si
