I remember seeing the BumpTop desktop concept making the rounds a while back but today I came across a bit more interesting version. In it, BumpTop creator Anand Agarawala walks us through the interface and it’s various features during his presentation at the 2007 TED conference. The concept is obviously in it’s early stages and while this demonstration seems to highlight some of the more frivolous features of the interface, I think a lot of the ideas could be very useful in a future OS. My favorite part is when he dares to insult the sacred cow of OS X, pointing out that it’s essentially a more “lick-able” version of the “same old crap we’ve had for years” (i.e. Windows). You gotta love the audience reactions. Video Link
Note: Since this video is now almost 2 years old, a multi-touch interface is notably absent from his presentation. In the time since the original video Agarawala has updated and has a nice multi-touch BumpTop demonstration here.
