Rainbow Ribbon
This JavaScript based drawing tool allows the user to create, save, and print digital drawings on the web. The tool follows the mouse wherever it goes on the canvas, creating a continuous line and a color trail that reaches from the initial to the current cursor position. The line and trail change color inversely in a rainbow-like fashion relative to X and Y position of the cursor on the canvas. A click of the mouse draws a circle of random size and resets the initial position from which the trail is created.
A click also prevents the trail preceding it from changing color with movement of the mouse. There are four user selectable blending modes to change how the color trail interacts with what has already been drawn on the canvas.
