Building a “Recording” Warning Sign

I'd like a circuit to power LEDs or an electro-luminescent display to be used as a "Recording" light in a small studio. Ideally, the sign would come on fully for several seconds at first, and then flash on and off slowly, ramping the voltage to the display or LEDs up and down, so as to create a soft blinking display.
