So I just randomly wandered in here via http://www.indiegamejams.com/ and thought I'd like to offer my services. I was looking for a game jam of reasonable length I could participate via the Internet.
Previous projects include VRjam 2013, where I did the music and sounds for Windlands. That project is still ongoing, as we are working to make the jam demo into a full game. There's plenty of gameplay videos on youtube if you wish to check that out. I've also done some song challenges in the Propellerheads user community (makers of the music software Reason). Usually it was a couple of weeks to make a song from scratch, using a limited toolset. You can hear my work on my soundcloud page for example, or download and play the demo of Windlands!

My contribution would be mainly music, although I have worked a bit on sound effects before as well. I'd of course also be happy to discuss design and ideas too, playtest and nitpick about ultimately pointless details that need not be prioritised when in a tight schedule. I know Unity just enough to have a superficial conversation (I did a couple of the tutorial games from Unity website).
I'll try to keep an eye for the forums here, so feel free to contact me if you are interested! I'd like to have a short side project to learn working with games, and also to hone my workflow and get in the habit of finishing things.
