Use your body to move in any SteamVR game that uses trackpad/joystick 'free locomotion'. VRock to increase immersion, get fit, free up your hands or just to fulfil that desire to look (even more) silly in VR!
Fully functioning demo but time limited before a cool down period is activated. VRocking may not be for everyone and games the use free locomotion have subtle differences in how the movement is handled so the demo should give you a good idea how the app will perform on your chosen hardware / software combo
