Just a pen creation. Right arrow to increase pen size and left arrow to decrease pen size. W and D to change backdrop color. Space to erase all. Hold down arrow to pause. 2 is default pen size.
You can make weird images using turbo mode and arrows. Tip: 1. Hold space. 2. Change pen size to 4, 6, 8, or 10. 3. Watch the lines go back and forth. 4. Hold down arrow without space a few times and look at the image.
