My Stepfather was a photographer when I was growing up, and consequently I spent a good deal of time in the darkroom of our local newspaper. They had these fantastic glow in the dark timers to keep track of film processing (ohh the good old days) that looked exactly like this one from Kikkerland. While this one seemingly lacks glowing parts, it is magnetic which makes it easy to stick on your fridge, and it's only 1" thin.
