Larry, Thanks for making this. I'm sure you have already put a lot of work into it... but i get nothing but a blank bitmap. No rings at all.

The program downloads a .BMP so it's PC centric, I think. The idea was to use the program to generate a zone plate image and then take it to the bureau to have it put to film. They charge about $15.00 for this. I haven't tried it out yet so I don't know how well it works. I'll be visiting them on Friday and I'll drop it off then.
