Tool Jam 5
Short one today!
I really like Game Jams. They're a great way for creators to practice their skills, get some small releases out, or even prototype some new, larger games.
Recently I learned about on that ended just two weeks ago: Tool Jam 5. This is a really neat collection of various tool. The modern Winamp is very well done, and the D&D Assist Tool will make planning my games much easier. I'm also intrigued by the interactive fiction prototyping course. The world could use more IF, as far as I'm concerned.
Check it out, and if you're looking for more there are 4 other jams in this series. That's dozens of tools, for free!
