Press The Flag + shift (to turn on turbo mode) and then the flag to clear the screen. Pressing any of the arrow keys will create a gradient starting at the side respective to the key and countinuing to the opposite side, black to white. You can change the pen size to change how fine the Gradient is, and do multiple gradients at once to create 3D-looking images (not on opposite sides). If there are any bugs, press the flag or space to clear. If the image looks coarse, then use the same gradient again.
