Now that Kinect has been cracked open so that anyone with a PC (or Mac) can mess around with its code, people are free to improve on its current capabilities. Like this guy, who has "multitouch" working on the camera.
In this demonstration video, we can see how user floemuc has been able to get the camera to recognise both his hands as input devices, which means he can then swipe pictures around just like Tom Cruise is able to in Minority Report.
The pictures aren't as sexy, nor are there any red balls or jetpack chases, and in many points it's even incredibly glitchy, but remember: baby steps, people. Baby steps. We have to start with a gallery of cherry blossom pictures before we can move on to solving pre-crime.
