Make circles! While the world spins round and round all you have to do is just press the space bar when the spinning bar is at the right place to make a circle. At first it’s easy, the bar oscillates with a period of pi seconds (3.14 s^-1), giving you plenty of time to make your first circle. But it won’t be easy for long! The difficulty increases every pi seconds: The speed of the bar increases by 3.14% (pi %) each time, until it reaches a frequency of 3.14 Hz (pi Hz). Once it reaches that frequency, the speed of the bar decreases again, until it reaches a period of pi seconds (3.14 s^-1). It sounds complicated doesn’t it? If you try it out you’ll see it’s more addictive than complicated.
