Draw along one of the outlines and my program will try to guess what you've drawn. My program is very strict, so draw carefully or have all of your circles called squares!
I was sitting here and I thought: "The distance from any point to a circle is the same. Making a circle detector should be simple." Well, I'd forgotten about the fact that humans aren't the best drawers. So, after some adjustments for different radii, I made my best attempt at a circle detector.
