My friend Anne-Marie makes stained glass and she made a nice piece for a recent show entitled Cave Gallus which is “Beware of the Rooster” in Latin. She had some back lighting in it at one point which was very popular.

I just rigged up this system with three LEDs, a 50ish ohm resistor, about 6′ of two conductor wire and a 9V power supply. Came out really nice.

I experimented with a tissue diffuser. Worked a bit but more experimentation is necessary.
