Monokai
I just checked out the new Dutch CC CD/DVD released under the Creative Commons license. While I was there I found a great piece of music done by Monokai. It's kind of old C64 game like music, you like it or hate it. I went to check out Monokai's website and I've spent a good 30 minutes playing with it.
The website is filled with music, photo's and electronic games, and is fun to play with. Go check it out! Nice quality!
