Possibly an overstatement, but here's a vid of some programs that the devs are messing around with using the PSEye:

A brief summary: Basically the devs are drawing landscapes and possible 2D level designs and placing it under the camera. The image is recognised and can be interacted with. Creating a 2D platformer games using your drawing skills could be a possibility!
Now, the video shows a tech demonstration and not an actual product, but as it says in the blog they could easily create the program for consumers. It's pretty revolutionary stuff...
