I should say more about the program I used to make these pictures (this one's generated from an algorithm, not, as the earlier one was, a computer treatment of a pre-existing digital photo). Some interesting aesthetic issues are involved (not only Is It Art, that is). But for now here's the picture. If you click on it, it will take you to my flickr page, where, if you so desire, you can see a larger version, plus the other photos (only three total so far) I have there.
