When it changes the desktop background...

PLEASE TELL ME WHAT TO DO, I CANNOT DO THIS APPARENTLY OBVIOUS PUZZLE, THE WALKTHROUGH LITERALLY SAYS "it will change your background, solve the puzzle" I DON'T EVEN *SEE* A PUZZLE ahem.

Where you are and what you're supposed to be doing would be handy to know. As far as I know the desktop background corresponds to a puzzle in the second area's ruins.

In the Glen. The same building where you find the dying plant girl, there's a computer. It changes the desktop background, and you have to find something there, but I can't see anything.

There's a floor tile puzzle somewhere in the ruins where stepping on various tiles will light up the floor. Guess what pattern you have to put into the floor to solve it
