The color pattern will react to the position of your mouse. You can change the variables to customize your color pattern. In style 1, the color/shade variable controls the pen color. In style 2, it controls the pen brightness. If you press the X key, the color/shade variable will change automatically untill you press X again, or until you change styles. Press space to show or hide the variables Press B key to switch between black or white background. Click anywhere to clear the screen. If you want it to react faster, try turbo mode (shift + green flag). If you move your mouse around the screen really fast, it creates some very interesting patterns.
