If you're reading this, there's already a good chance you know about Symphony of Science: John Boswell's amazing collection of videos where he has autotuned the words of scientists and science promoters, creating a lovely and beautiful series of paeans to reality.
John has done something pretty cool: he's taken the audio from ten different pieces he's written (plus one bonus track) and put them all in one place to download. These are high-quality audio files, and the neat thing is that in exchange for the download he's asking for donations to his project, whatever you think is fair. You can download them for free, but he's hoping to raise funds to create more videos and promote more science.
I really love this project -- as do a whole lot of other folks, too -- so I expect his experiment in quid pro quo will do well. As you might remember, one of the songs, "Wave of Reason", has a line in it by me, too. I'm still really proud to have been included in this project to bring a love of science to even more people.
Tip o' the baton to Noisy Astronomer.
