I have to tell you, I loved your block. I thought it would look great as a repeated block, and I just had to see... so I made these. The first one is just randomly rotating the block. The other two are more deliberate, for a kaleidoscope effect or whatever.
(Oops, these are huge file sizes. Admin, let me know if I need to redo these as .jpegs.)
Oh well, I see that the "random" one turned out to have its own kaleidoscope pattern, but it's different that the other two.
