skinterface

If it's not already called this, it should be. A competition entry (probably a way off due to power and processor problems) involves a flexible, touchscreen interface (composed of a blood-powered cell, processor and silicone touchscreen interface which stimulates a matrix of charges spheres).

The interface, as well as being powered by your own blood (which it could perhaps monitor for health issues), would have a bluetooth interface allowing you to control all manner of devices through it.

Price? Availability? I really want one - but i think it might be some time off.... :(
