Looking forward to giving this a try when all my parts come in ;)

Thanks!

Maybe I'm just not getting it :(  I do have it setup as you suggested, but seem to always be getting the same colors across the 4 RGB LED's.  Can you show me a bit of example code where I can differentiate each RGB?  I'll keep trying here as i have the circuit setup like you suggest (except with a 74HC595)

With a 74HC595 you need different data, walking a 0 across the outputs for the different rows.

B11101111
B11110111
B11111011
B11111101
B11111110

with the TPIC6B595, the output goes low when the input is high.
with the 74HC595, 1 in = 1 out.

I did get that working, thank you very much for the help and direction! :)

Curious now... I have 20 RGB LED's that will be mounted around a circle opening (in wood) with LENS Caps to protect them.  Now I am wondering, how best to wire them?  Is there any good way to have a wiring harness that would go from each LED back to a central board?  I guess I'm thinking more like a PC board where all the wires are removable.  I've been looking around and I'm sure I could make something myself, but just curious if there is a 'typical' way to do this.
