A nice look back at 2009 from Nathan at Flowing Data (who definitely knows a thing or two about this stuff!). Each is worth exploring, although some are definitely more serious than others. I think my favorite on the list is the Open Street Map animation and I happily put aside my concerns about 3D globes since the point is not any one piece of data…it’s the qualitative impression left by the explosion of a free, bottom-up data.
