Use turbo mode! I watched a cool video on how somebody hears color, so I figured I'd try making a program to simulate that. Keep in mind, please, that this is inaccurate, slow, and generally not very good. It doesn't support all the different colors - only red, green, and blue - so you only get three notes, and the colors don't have the right note sound so.. it could use some improvement! ;) I did find a weird bug with Scratch though - download this project and open it in the offline editor, and you'll notice the squares light up from newest created to oldest in chunks of ~80, while in the online version they all light up at once. Use the up arrow key to increase the size of the capture area, and the down arrow key to decrease the size of the capture area. Note that the space between the individual squares will also change based on the size - there's always going to be exactly 100 clones.
