+I was not so happy with the pixel manipulation. Online, I found an effect that I really like. It’s used for motion tracking. If the object is still, you don't see it. If it moves, you can hardly see the outline. If it moves faster, you can see more and more.

+I simply changed the color of the image with jit.unpack and jit.pack. For capturing a snapshot, I used the microphone which is triggered by snapping fingers or clapping hands. Every snapshot should be saved directly, but somehow this didn’t work. You can save it manually right now.
+Here is the patch [[:File:210609_Moving Fast.maxpat]] and some screenshots
