Valve's Alan Yates (@vk2zay) spoke with us about the science and technology of virtual reality.
Elecia looked at the iFixIt Teardown of the HTC Vive system as she was unwilling to take apart Christopher's system.
Make Magazine talked about Valve's R&D Lab. This is important in case you want to work at Valve (they are currently hiring for EE but if that doesn't describe you and you want to work there, apply anyway).
Alan also has a website (vk2zay.net) though it doesn't see much updating right now.
