These were created using an invisible image in the background to pull colors from. Wherever the mouse cursor on the image was, it would draw a line that same color. The curve of the line is determined by the brightness and hue of the pixel. The end point of the line is based on a timer that is running while the program draws. It sequentially moves left to right top to bottom for the end point, then repeats.
