A patent filed with the Patent & Trademark Office shows a range of crazy motion controller peripherals conceived by Sony, some of which could end up in your living room.

KotakuPS3 motion controller add-ons. Some have been previous divulged like combining two motion controllers, but a few are downright bizarre.

One such configuration involves a thumb reader that gathers biometric data for gameplay. In English: the peripheral reads your pulse, body temperature, and more when you insert your thumb. Sounds remarkably similar to Nintendo's Vitality Sensor - not that it was inspired by that, no, not at all.

Glib assessment aside, it's important to note that Sony's patent application is not a guarantee of an actual product. Companies do this sort of thing all the time to protect their research. The only thing that is certain is that the regular PS3 motion controller will be out sometime this spring. That looks crazy enough.
