And you thought NVIDIA's 3D Vision was the height of 3D PC gaming this year. Coming straight out of the UK is Cambridge Consultants' Suma, a controller resembling a rubber stress ball which responds to the user's pressure and grip.

It carries out the commands thanks to built-in sensors, and is able to move the cursor in three dimensions, making it an easy pairing with PC gaming. Normally this sort of interaction is done with the use of a glove laden with sensors, but thanks to the inner workings of the Suma, the PC can translate each squeeze into software-readable form.
