The Uncertainty Machine - stuck in the dark!

[hmm, I can\'t login]

I'm locked in the dark room.  I looked at the walkthrough and it says the lightswitch is roughly in the center of the room... The only ? symbols I can find say "this thing is big and heavy" and "this seems to be a wall or something".  Any more specific instructions would be appreciated.

NOTE TO GAME DESIGNERS:  Please, for the love of "Bob", keep the puzzles based on thinking things out and not on being lucky enough to randomly click the correct pixels on a black screen.  

(This has been a fun game, otherwise)

I assume that after three weeks you'll have solved this one, but for anyone else with the same problem, the switch is halfway down and 1/3 of the way from the left.

Halfway down and 1/3 to the left isn't helpful enough....where is the switch?! It is not in the middle of the room.
