Symbol Eclipse

My sister recently told me about a kid she knows. He had a non-functioning toy camera, and after pretending to take a photo he was turning it around to show other people the non existent screen on the back side.

I am not sure what to call the period of time when designs and interaction sort of eclipses itself. The story reminded me of my ongoing fascinating with the "Save" ico; (A floppy disk!?) I challenge anyone to come up with new kinds of graphic symbols which mean "save".
