Hyperkin's "Sports Victory Set" of PlayStation Move accessories has a couple of problems. First, they are a bit ridiculous looking. (But hey, waving a dagger around could be fun). More importantly, they will mess up the whole damn system.
PS Move's technology hinges upon its ability to spot the LED sphere at the end of each controller, which allows for accurate tracking. But block a clear view of the orb with, say, a giant attachable plastic ping pong paddle, and you you will probably run into some difficulty. Luckily, Hyperkin's "Special Ops Shooter" snap-on accessory looks like it might not impair your Move's sight. [Hyperkin via Joystiq]
