The Kinect demo was also cool, although I'm wondering if it wouldn't be easier and more intuitive to just touch the screen. I guess I could see this in a scenario with a -massive- screen though, but even then: wouldn't it be easier to just use a secondary device to control the panning and zooming, rather than these gestures?

Then, how about this? http://research.microsoft.com/apps/video/default.aspx?id=185440&l=i
