I just thought I'd post a link to the Secret Santicore PDF, for any of those who haven't seen it elsewhere. I didn't contribute to the project (didn't even really know about the project, although I saw a couple references to the phrase "secret santicore".) But there are a couple familiar names in there, and I've seen a couple blog posts by contributors describing their contribution.
Basically, it's several short adventures, lots of random tables, and a couple other useful bits. It's mostly for D&D-ish games, but those of you doing Shadowrun or Mutant Future will find a couple things in there as well.
