Pretty good, but hard to really see the patterns at 10x10.

Later I redid it with matrixed displays, MUCH less hassle, and put it
in a nicer frame with red plastic over it.  It's still around here
somewhere.

Was in pittsburgh this weekend, saw LED based billboards in full color.
Boy, things have come a long way.
