Mike Swanson has a cool idea for the PDC this year. He wants developers to show off what they're working on. Got something cool? Make a short video demoing it, and during PDC, they'll show it in a video with a bunch of other cool projects.
Go read about it and if you have an idea, then send in a video. I'll look forward to seeing it once it's released to the masses (I'm not going to PDC).
And if you don't want to read his post, listen to Mike and Thomas Lewis talk about it on the PDC '05 Buzzcast.
