I think I originally submitted it as "Facebook Design: VR Resources", but the mods did the HN thing where the title changes to directly match the original. This is in no way meant to be a general VR knowledge dump, it's specifically a set of resources that Facebook has produced targeted at designers that traditionally work on web and mobile design and are new to VR UI.

The most interesting thing on the site is the publicly available version of the VR hand models used in the Oculus home UI and all of their games and demos, which were previously only available if you had a relationship with Oculus developer relations.
