It’s not every day you get to visit a booth that features two great tastes that taste great together. To wit: Razer’s booth was pretty amazing and featured the unique Hydra 3D interface plus some exclusive gameplay from a modified version of Portal 2.

What is the Hydra? Once called the Sixsense, it’s a 3D interactive system for gesture-based gaming. You move two controllers around a magnetic orb that senses your position in space and allows you to do odd stuff like “stretch” boxes in the game. It’s an odd thing to see true pinpoint accuracy in a game like Portal 2 and it’s particularly unique to see motion control for the PC. In all I think the Hydra was one of the coolest things I saw at the show and can’t wait to try it.
