Ok, so here is what I have planed. Ethan, tell me if I need anything else. the big ugly thing in the 2nd image is the diffuser. Some of the alignment may be off but this is just a rough layout. Obviously the final prod will be somewhat different as I lay everything out.
You can see the real desk in the earlier images, this is just the one that came with the program. It is the right shape geometrically from a top view.
