The button: social experiment driving Reddit crazy 11 years ago
Do you have anymore details on this game? I can't find anything on it, but it sounds interesting.
I agree that the game you describe is more personable, but /r/thebutton does have an air of mystery going for it. The simple premise has left room for a lot of interpretation. Is it better to press the button, or stay gray? Which colors are the most desirable? What will happen after the timer runs out? etc.
