I like it. I like the seemingly randomness of it. The only thing is there are a couple of places where the same color shows up three times in the 7 blocks across. I'll have to see if I can switch some out with each other. I'm finished with my tax returns, so am now off to the design board to lay out a few rows and see how it looks in person. My board is not big enough to lay out the whole thing, but should be able to get 4 rows up at a time. (The blocks are 12 in finished). I've got an idea for a border, but need to see if I have enough colored pieces left to do it. I was thinking of this, where there are colored squares in a zigzag like pattern around with the white backgroud:
c-----c-----c--
-c--c--c--c--c-
--c-----c-----c
I'll have to play with it.
