非自然

非 = 三 + 丿 + 丨 : Mnemonic symbol: a negative film (photography).

Frankenstein's monster (f) made an effort to photograph the Eiffel Tower (ei1), but now his negative (非) is a big mess. In front of the tower he set up a camera on a Cartesian coordinate system (三) as a tripod, and he attached a banana (丿) and a dinosaur bone (丨) to the camera so that he can finely tune the angles. All was for naught as he now holds the messed up negative in his hands.

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

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

然 = 灬 + 肰 : Robinson Crusoe is grilling some dog meat on his BBQ in the anthill's kitchen, but it's hard to do it correctly because of all the animal rights activists. They think it's not right to grill dog meat.
