no-dice: Generate random numbers with strictly a pencil and paper by drawing simple curves and counting the number of intersections in the curve.

Obviously, it's not secure, but it's a creative way to get a quick unbiased random number without too much trouble.

Of course you could manipulate it, so it requires you to be honest about not paying attention to your curve or intersections, and just drawing freely.

Just don't get too crowded or it can be difficult to count.

@atoponce Unbiased? I don't believe that. I'm expecting the raw distribution to be closer to Gaussian centered at 6 than uniform, and that can't be corrected by a simple modulo.
