How do I pass the grid of stones to the diamond?

Solution 1:

There is a circuit box on the left when you enter the chamber that you need to activate. Every time you activate, some of the red lights will turn green forming a path from the bottom to the top. Each of the lights corresponds to a tile on the floor, the bottom row being the closest to you. You must follow the path indicated by the green lights. The path will only last 30 seconds though, so if you're alone, you must be quick. The path changes each time you use it.
