Okay, guys. I'm not picky! :-)

So, Tom, can we incorporate your stuff into the "Two-row-of-lights" plan? I
did some measuring this afternoon, and it looks like the optimal number of
lights in either row is now TEN (not 15) -- so I'll need 20 lights, total,
in two rows of ten.

They need to be sequenced together, so that they "chase" from the door
toward the lobby reservation desk like the airport "rabbit." The two rows
should be sequenced together, so that they blink as one unit.

Need any other info?

Hi Jay,

Two lights per "stage" no problem. Just connect each pair in series,
then to the proper controller output. With 10 stages, you will have
11 leads coming back to the controller. One positive "bus" tying the
+ ends of each stage together, and one lead from the - end of each
stage. You mentioned maybe having a motion detector trigger the system.
The previous tennant of my office left behind a passive infrared
detector from his security system. I probably can integrate that into
the system as well, and adding a pot to set "turn off delay" will
give you an "auto start with time delayed off" function.
There will be outputs to drive up to 16 stages, so you would just
use the first 10 for your setup. Should be pretty cool!
