Harmony starts the user off with a blank canvas to experiment with. The program has two colors, The pen color and the background color, which you can change. There is a drop down menu with different pen textures that you can choose from including sketchy, shaded, chrome, fur, long fur, web, simple, squares, ribbon, circles, and grid. The speed of the mouse controls the size and weight of the pen.

Another program from Mr. Doob that has some nostalgia for all of the kids who played with those paint spinners as kids. Spin Painter spins the screen, at a speed chosen by you, and plops down paint of different sizes, also controlled by you, to create designs. The only thing about this program is that you cannot choose the colors you use, they automatically cycle through, but it is fun to play around with nonetheless.

When I tell my students about Mr. Doob: Voxels I compare it to mine craft because they both use colorful blocks to build worlds. Voxels gives you 9 colors that you can use to build with. Click to add blocks, shift and click to remove blocks, drag the screen to rotate your work, and press 0-9 to change the colors.

You can also use the arrow keys to move your entire design around.
