Projects for old 35mm point and shoot cameras?

I have a few 35mm point and shoot cameras and I see them in thrift shops, yard sales, and flea markets all the time. Are there any cool ways to make these into something else or scavenge the parts for other projects?

lots. coilguns are the coolest but you can make flash traps, strobe lights and other stuff to. just search coilgun and you will get lots of results. they say use disposable cameras but any regular flash camera will do.
