FYI - Here is a zone plate image:

I haven't done alot of Zone plate work, but I haven't noticed the "distortion" that Judy described. Definitely a very soft, glowing look, with kind of an "internal" sharpness, for lack of a better term. You can get zone plates in various focal lengths from the pinhole resource. They are more difficult to "DIY" than a pinhole.
