To me, anything you say on Twitter is said in an instant, and if you hear it - you hear it, and if you don't - you don't. I sometimes forget that Twitter is permanent, archived, indexed and searched. Christopher Baker's project, Murmur Study, helps put that into perspective. He has created two installations that print out local tweets on long rolls of paper and drop to the museum floor. Creating an "absurdity of the physical archive" of conversations.
I've seen lots of Twitter visualizations, but none quite as thought provoking as this one. Fantastic idea. (Found through ComputerLove).
