One of the fundamental questions that we had was, well, how big should the icons be? And so one of the engineers on the hallway had an idea his name was scott hers. He was doing work on spring board, the icon launching programme himself. The game went like this: You would launch the game, and there was a minimul user inter pace. All it was was a rectangle on the screen that was a random size and a random position. It didn't tell you if you did, if you if you succeeded or failed because the idea was just go, tap the rectangle as quickly as possible.
