I may be too stupid for some puzzles in Antichamber, but I'm not too stupid to find a bunch of secret rooms (well, I GUESS they are secret since there is nothing to do there)
Remember that pink block Ryan and Patrick "chased" during the Quick Look? Well, there are a bunch of them and I guess something special happens if you find them all? Who knows. But since I will never ever ever ever find all of them by my own I guess a thread would be a good idea?
-Window of Opportunity: If you run back and forth between the red/blue/green room eventually you will find a pink room.
-Link in a chain reaction: Just run straight ahead to the glass and turn right. The wall will disappear.
-The butterfly effect: Turn back, run throught the energy field and jump down the elevator.
-Managing ressources: Go through the left door and you will see a disappearing stair. Now instead of going throught it, build your own staircase with blocks and go upstairs.
