Inside Oculus: Rare photos from the early days of Facebook's virtual reality pioneer

Jack McCauley's research lab in Livermore, California, is hallowed ground for any virtual reality fan.

McCauley was a founding engineer at Oculus VR, the virtual reality headset maker that Facebook bought for about $2 billion last year. He told Business Insider that the team filmed Rift's original Kickstarter video in his facility and designed much of its first development kit, DK1, there, too.

After hustling away on the headset for about two years, McCauley left Oculus shortly after the acquisition, but continues to work on new virtual reality projects in his lab today.
