A remix of the remix with faster rendering and MINIMAL ADVERTISING! I don't want the comments flooded with advertisements. Explanation: It gets the distance from each pixel to both the circles, then runs it through the selected function. If the result is below the threshold, the pixel turns black, otherwise, it turns white. The options are d1 + d2, d1 - d2, d1 * d2, d1 / d2, d1 % d2, max(d1, d2), min(d1, d2), abs(d1-d2), sin(d1+d2) I made it so the rendering is much faster by lowering the resolution when you grab a point. This allows much faster frame rates.
