VR is attracting a lot of attention--and money. Virtuix announced $3 million of seed investment for its treadmill--far more than the $1.1 million they raised on Kickstarter.

Virtuix Omni, a Kickstarted treadmill for gamers, allows gamers to run around in virtual reality worlds--without walking into a wall. It may seem odd, maybe even silly at first, but seeing it in action has made me a believer.
