Worth checking out: Live Labs Pivot
Don't you just love TED (no, not the creepy guy from across the hall)? Well I do as it's a very inspiring nonprofit initiative - and their TEDTalks are released under a Creative Commons license (which also has my love), so they can be freely shared and reposted.
This TEDTalk is "Gary Flake: is Pivot a turning point for web exploration?" - and yes Gary, I do think that Pivot could be that if you guys keep working on it. Let's see Gary give a short demo....

Are you hungry for more Pivot info (you should be) - have a look here (only works if you got Silverlight installed, sorry)
If you want to try Pivot yourself you can find it here
Curious about who Gary Flake is? Well on his own small site it seems like he's the "Darth Vader of the Internets" but he's also more formally the founder & director of Microsoft Live Labs with a pretty impressive background (maybe I'm just easy to impress). Find Gary's CV here and judge for yourself.
