Virtual reality headsets like the Oculus Rift will hit retail markets next year, opening up a new way to play games to a lot of new people. But while head-mounted displays will make it easier to look around at game worlds and feel like you’re present within them, on most VR kits, you’ll still move around in games using a standard controller.

Unless, of course, you’ve got some cash to spend. Then you can get the HTC Vive—a VR headset that also uses cameras to track your movement through space—and the Virtuix Omni treadmill, which lets you run around in a video game without accidentally falling down the stairs or impaling yourself on something in your apartment.

The weird-looking treadmill lets you walk or run in any direction, which is a pretty cool idea. Of course, it’ll run you $700 when it releases in the first quarter of 2016, around the same time as all the various VR headsets about to hit the market. But it’ll come with a harness that lets you pivot fluidly, special treadmill shoes with “tracking pods” that keep the location of your feet dialed in to the game, and TRAVR, the new game demo shown in the video up above. And the Vive won’t be cheap either, nor will the computer you’ll need to run games on it. But it does all look cool as hell.
