gollark: I *think* once you create a 3D object around a center point its origin is fixed until you recenter it, but obviously you can move.
gollark: I think you don't actually have enough data to. Unless you constantly use GPS.
gollark: You'd probably want them to only be clickable with a keyboard out though.
gollark: It's a shame it'd be so annoying to register clicks on 3D objects when you're using the keyboard. We could have virtual 3D-positioned touchscreens.
