First of all...
Click in the applet area, move your mouse pointer and try these keys: "1, 2, 3, 4, 5, 6, 7, 8, 9" and "0"

Use "w, r" and "o" keys to change source image.

Use "+, -" and "a, z" keys to catch your own motion picture.

Use "d" key to change algo.

If the picture gets too fast...

That's all :)
