I posted about this before, but it’s worth mentioning again. This year NIME is being held at Goldsmiths and will include an open day and Hackathon. The Hack has two challenges, set by Heart n Soul (the SoundLab project that I’m working on) and also Drake Music.
You can read the challenges at the hack space blog, where you can register too. So if you’re going to be there, say hi!
