Hello Piet and everyone,
The one from the eprint may have a SPIE copyright on it. Again not sure here.
Had a go at making a new one for you but my old (windows) machine will no longer boot. Need to spend a bit of time getting Povray working. Anyone got POVRAY working on a MAC?
Here is one I'm sure has never been used, so the copyright is mine. Is this the kind of thing you are looking for?
