Look at the spiral and enjoy! You could slide the angle, speed, and pen size around and you may get crazy results. Down arrow key to hide variables and ball, and up arrow key to show it again. Right arrow for pen up, and left arrow for pen to be back down. Double press keys 1, 2, 3, 4, 5, or 6 for some cool formulas that I found. Key 0 just resets it to the default spiral. Space to clean.
