- Leaving grid in, but going to take it out of the collidables array
- Working on room!
- Room is working thanks to the fantastic Constructive Solid Geometry
  plugin - https://github.com/chandlerprall/ThreeCSG
- Now working on room details including window (might use water effect for
  window material as that'll look sexy)
- Will see if I can then refactor this up into a method and re-use on the
  solar system scene.
