I went to Dorkbot DC yesterday. Goodness, there were some great presentations. Before I gush, here's a description of the group for those of you who may be unfamiliar with them:

Dorkbot DC is a monthly meeting of artists (sound/image/movement/etc.), designers, engineers, students and others in the DC area who are interested in electronic art (in the broadest sense of the term.)

Basically, people have goofy ideas, mock some stuff up, and come in and show it. Some projects are great, some less so. I've seen a guy presenting on how to build a megawatt laser at home for under $1000, someone else who made a USB voodoo doll that reacts differently depending on where you needle it, a guy who made techno out of the human genome, and another guy whose art is making quilts out of circuit boards. Some of it has been incredible, some hilarious, and some completely confusing.

Yesterday's was pretty much 100% excellent.
