John Carmack gave a succinct review of Bigscreen Beyond. Beyond is an ultra-compact and ultra-light SteamVR headset designed to enable truly comfortable long duration PC-based VR sessions. The key drivers of its tiny size and light weight are the use of OLED microdisplays and the fact that each unit is customized for the buyer's face and eyes instead of being adjustable, based on an iPhone 3D face scan. It was announced in February and two weeks ago, Bigscreen announced production had begun.
