I realised I never mentioned the idea! We are working on a VR maze on a small planet using impossible spaces to make the world feel strangly full. I've just completed a keycard prototype for doors so we can introduce some kinda dynamic maze. Tesrym has given us some textures and basic models to start using. NegitiveZero is away at the moment, but has been getting on with his spaces prototype. Stream is up here: https://www.twitch.tv/kaffse
