The bottom right of my screen is an image dump. I see something that I think might make a good icon some day, and I leave it there. It stares at me so I don't forget it. Of course, I learn to ignore them, and the images pile up. So, this morning, it was time to clean up. Some got deleted (not as cool anymore), some were left for another time, some were worked on and discarded...and three new icons emerged. Available for anyone's use.
