Use Turbo Mode! (Shift-click the flag to turn on turbo mode. Do the same thing to turn it back off.) Watch as circles, triangles, squares, pentagons, and hexagons of all colors, sizes, and side thicknesses fill the screen! You can press space to switch between a black and white background. It's also 100% pen. I really didn't know what I was going for here.
All scripts by me.
