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.
