I created a simple array of 20 rectangles with random widths (heights start at 0.001). Each mouseclick creates a white rectangle at random coordinates, which then stretch vertically to the bottom of the screen (achieved by incrementing their height by 0.17 per frame). All the while, the background is flashing every which color and the white rectangles slowly drip to the bottom of the screen. The resulting images resemble some kind of negative-space cityscape, offering calm and shelter from the storm of epileptic colors. It looks cooler in stills than it does in motion.
