Video: See some of the many prototypes inside Valve's VR lab

Make magazine recently travelled to Valve's headquarters in Washington to check out the game company's VR efforts, and they brought some cameras with them.

Now Make has published a photo-filled feature about the trip on its website, and part of that feature is a 15+ minute video (embedded above) of various VR prototypes inside Valve's VR lab.

It's an intriguing (if very guided) look inside the workshop of one of the game industry's high-profile bastions of VR research, and it includes a conversation with Valve VR engineers Monty Goodson and Alan Yates.

Yates, of course, recently estimated that as much as a third of Valve is now working on VR/AR in some capacity. That's reinforced by the fact that Valve has revived its Steam Dev Days event this year with a new focus on VR.
