Swipe your hand across your webcam to spin the wheel! You can edit the code in the arrow (the "Chooser") to change what you want each space to do!
The spinner uses a color coded "costume" for each space that is detected by the "Chooser" to determine what space it has landed on. You won't be able to see it, as appears for about 1/30 of a second, but this is enough for the "Chooser" to detect it.
