Is there any place where you can build LEGO stuff in a 3D viewer, then play with it (physics engine), and perhaps even with VR goggles in augmented reality?
This is probably my number one VR application I want. I don't like Lego CAD applications (physical feel of building is important) and don't want to/have the room for "infinite" sets. I've seen some prototypes of VR lego builders. If I had the time I'd absolutely do this as a hobby project, with a focus on VR interaction and feel.
Blockland[0] is basically this, minus VR. I would probably recommend staying away from the community, though..
