This looks better as a kitted piece, than the map seems to indicate.
I've been repeatedly tweaking a variant of Walker's "Double Fern" in an attempt to get a frothy-wave-type pattern. With this variant, I used 8 row blocks in this one instead of 16 row blocks, so that's why I called it "half-Double Fern-lette", because this one is only 8 rows per block, rather than 16 rows per block.
The 8-row version does seem to be more wavelike than the 16-row versions.
