I founded a little demo on my external harddisk drive, who I created 1-2 years ago. It includes c_move, so I thought, it's a good demo for this contest:

I think, it works on GS-free.
and how I said, thats a realy old code and it's very confusing...
I hope, there's a better demo in next time from a beginner, who realy needs an extra version from GS.

Cheers,
Hopfel
