Not my project, but David Bradley has compiled a Twitter list of scientists who are also musicians (or vice versa). There are now 35 people on the Twitter list, and the first 25 are also on his blog.
A few people on that list I already knew of, or had jotted down their name for my own project, so I’m keeping an eye on this.
(And if you’re feeling really bored, you can also follow me on Twitter. I occasionally get sick of it and delete all my Tweets and stay off it for a few weeks, but I’m using it at the moment. It’s more music than science lately, and a lot of moving woes. I’m moving to the UK in three weeks, to start a new job there, so selling my furniture is my current main project. Anyone want a coffee table?)
