I made up a simple macro which turns a network of points into a Escher style
impossible shape. The effect is not perfect but in some cases very nice.
I thought I would share the resulting images and see if any one had any
suggestions for improvements to them.
Also would anyone be interested in the macro I just made it up as I thought
it would be interesting.

Would it be possible to animate such an object with your macro? For
example, rotating it? I'm looking for something like this!
Anyway, great image!

Yes it is possible to rotate an object and animate it rotate and position it
with the macro some angle give problems but only a few and I am re-writing
the macro to get around this and imporve efficency.

I would certainly like to see this macro when you have finished it

Robert,
Very interesting!
As I have a page http://cage.ugent.be/~hs/tribar/ on my site concerning
Penrose's impossible triangle using povray, I'm interested in the macro.

Look at my signature! (if you haven't already).

Hello Jellby,
I looked at your signature and indeed: that's a very short and nice code
for the tribar!
