DIY Motion sensor for the PSP?

Sony's Dual Shock 3 controller (or so it has been tentatively called) for the PS3 will feature motion sensor support - so why not have a motion sensor on the PSP? This video shows a motion sensor adapted to work with the PSP. From what I can tell it's running the PSP game Mercury, and works reasonably well., although it's not the most sensitive of motion sensor devices.

It could be a homemade motion adaptor for the PSP, or, most likely an early development version of the motion sensor accessory that was being developed for Mercury before it's release. What a great attachment this would make for the PS3 - Who needs Dual shock 3 when you've got a PSP to use?
