Greetings, Scratcher Press spacebar to change the parameters, then press it again to render using said parameters. The brightness of each pixel is the sum of the inverses of the distances to all circles with respect to the their radii. (That's right, right?) Another quite old project of mine that I decided to dust off and share. I refactored and optimised it quite a bit, too, since to old code was... less than ideal. I didn't bother making them move though.
