Cool - do you know who is teaching it this year? I think Philip Ross (the mushroom art guy) has thought this class once before, but it doesn't seem like a very regularly scheduled class.
I've been tinkering a little with bio art at BioCurious and I wouldn't mind doing more of that at sudoroom. We've been discussing doing some events/classes/seminars with East Bay DIYbio, and this could fit right in there as well.
Actually, at the moment I'm trying to come up with some fun hands-on experiments we can do at the BioCurious booth at Maker Faire, preferably with all edible materials: agar-agar, red cabbage juice, bakers yeast, live yoghurt etc. Doing the experiments to figure out the best combinations would not be very artsy, but it's definitely something that can easily be done at sudoroom.
