There are 8 rooms, 4 in a front layer, 4 in the back that all form a cube with doors inbetween them. The buttons in the front rooms set the correct ones to the matching pattern and color on the hologram puzzle. Once its completed the front hologram turns into a lightbulb for use later.

I have no idea how to use this guide

I hope you don't mind, I've referenced your Guide in my Walkthrough,
Thankyou for the great pictures as this Puzzle is confusing to put into words
