For awhile, I was doing some of the PSPUG challenges. I've only just recently started trying a few again — as you can see, there was about a 2-year period during which I didn't do any. PSPUG is now PSPIZ, the PSP Interactive Zone.

Each week, one of the players posts an image— usually a black-and-white clip art image. Each player creates one or more images that somehow incorporate that image. At the end of the week, all of the submitted images are placed into a gallery.

Challenges are posted in the challenge forum:
