So the "falling" will be animated ?

I've not used bi-colours much, but when I did, those I could
find were relatively expensive and not particularly bright. If it
were me making this, I'd be looking at a couple of cheap high-
intensity SMT or leaded LEDs instead. Carefully placed under
a diffuser (which could be a thin sheet of transluscent plastic
under the front panel) you wouldn't know the difference. Apart
from the $$$ saved. And being easier to see. And using less
current. And being easier to assemble. And having more colour
combinations to choose from. But apart from that .... ;-)
