Go to Artomatic Now!
This will be a quick post. I'll write more next week, but I just got a preview of Artomatic and all I can say is go, go now. If you can make it this weekend, go, and keep going back. It's absolutely fantastic and you can spend days cruising around.
The hours are great and there are lots of performances in connections. Check out the details at http://www.artomatic.org/
To see some photo highlights, check out the Flickr photo pool
DCist also has a good write-up up.
