Tried a few spare LEDs in FT's BG tonite. About 6 warm whites, 3 green for the fish, and a red for the fisherman (notice he is another Furbs look-a-like? lol). Still about 8 normal 555's in there still.
I am going to get more and do the whole BG in LEDs, colored and whites.
Here is pic of the PF, added another 40 LEDs into it today.
The balls change color when they roll into the flipper area....electric blue lol
