自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

This character looks like a butcher's hook. In the space station, Joan of Arc wants to conduct an experiment about a sixth order chaotic pendulum. First she hooks a butcher's hook to a sickle, then sticks the sickle's end into a flute, and finally hooks the handle of a shovel into the last hole of the flute. She then swings the chaotic pendulum to observe its behaviour.

动 = 云 + 力 : Doggy Dog notices a lot of smoke when he enters engine's bathroom. Instead of thinking long, he acts quickly and moves to push the fire alarm button.
