Today Seesmic released Seesmic Look into their arsenal. This is a new style of app to immerse yourself in the twitterverse. Hit their features page for more details. Basically it gives you a more "floaty" view of your subscriptions, lists, things like trends, and other categories of items.
Looks very nice, though a bit slow, on Windows XP. Not unsurprising as it's optimized for the Aero experience in Windows 7, but doesn't allow some standard things like right click to copy a link. Ah well, a neat new view of twitter for sure. Wonder if this will make it's way into an iPhone (or other mobile) app. There was one for the iPhone that used a 3D paradigm, which was ok, but didn't catch on that well.
Announcement blog post as well.
