Throughout my (many!) experiments with this, I noticed a kind of repeating
diagonal pattern of the bricks, when using just <.5,0,.5> for the warp
'offsets.' I've attached an image to show this. Choosing <1000.5,0,999.5> (or
other similarly larger offsets) *seems* to make this pattern less noticable, or
shifts things around to be more random-looking. Or something. ;-)  Honestly, I
don't really know for sure why this appears to work. I *think* it shifts the
entire cells pattern in space, before the next brick is 'created.' My guess,
anyway.

However, I don't see this diagonal pattern in your own image.
