From Digg Lab's:
Digg Arc displays stories, topics, and containers wrapped around a sphere. Arcs trail users as they digg stories across topics. Stories with more diggs make thicker arcs.A really great looking flash movie showing active Diggs updated and added on the fly by by users! I video captured 2 minutes worth of video and saved it as a MOV for both PC and Mac users. Check it out yourself here!
