Came across this site today courtesy of Steve Rubel.  Twipick let’s you view the masses of Twitter photos posted on any given topic.  Uses all the photos posted on Twitpic with a particular tag and groups by trending topics so v easy to use.

Was a fun way to watch all the London Marathon photos being posted this afternoon. Can see this being really interesting and informative in the case of a larger world event – a digital rubbernecker’s dream maybe?
