Infochimp.org is now in -- whatever comes beyond Zebra but before Alpha.
One of the major impediments I've found to doing interesting visualizations has been the chore of getting data out from behind bureaucratic barriers and into open formats. Infochimp.org is founded on the idea that that this chore shouldn't be repeated over and over again. There should be a good source of free, open datasets -- raw data, with traceable provenance and recognition of the people who collected it, ratings for quality, and powerful index and search capabilities.
Eventually it will build to the idea that there's really only "One Dataset" -- that with a modest and attainable collection of "Join Tables", semantically-labelled fields, and analysis tools, you can nimbly pivot any collection of data sets that meet on a common axis. This one has FIPS codes while this one has country names? And you're tying that into time series given as UNIX epoch seconds, but your database demands SQL dates? No problem: datasets from infochimp.org will arrive having fields imbued with type, representation and measurement units information. You can build tools that simply, straightforwardly work with the meaning of your information fields and not their myriad representations.

The Vizsage project blog has news about the Vizsage project, other software I'm making, and anything interesting I figure out about Flex and Actionscript:
SubZero shows how the geography of Washington DC would appear from each station if distances were measured using subway travel time or cost. Demo Source Docs
For the 2007 season, the clever folks at Major League Baseball have been recording the trajectory of every single pitch and batted ball, along with the players, location, and complete game state. (Right now about half the stadiums are covered, but more are being added). Mr. Mxy lets you explore the MLB Gameday PitchFX data in an intuitive way.
