If there's one thing that makes anything cooler, it's lasers. califrag from QJ has developed a proof of concept (seen above) that allows you to point a laser at the PSP screen and have the on-screen cursor follow your movement. Although it requires extra hardware, such as the PSP camera, the potential is really exciting: imagine a light gun game for your PSP, a painting application, or some DS-styled "pointing games." Once again, the homebrew community has thought up something truly innovative and surprising.
