Every year or so i decide it's time to try something new and different (e.g. jazz piano, oil painting, modern dance, aerial dance [thanks to rebbyribs], acting). I think my next thing will be contact improvisation. I've wanted to try it for a long time, ever since Guido van Rossum first suggested it to me at a Python conference several years ago, shortly after he got married. (He asked me whether i had a girlfriend, i said that i was single, and he explained enthusiastically that contact improv was how he had met his wife.)
There's a festival coming up. It looks like fun! I want to participate.
