Where did the yellow-hammer cow come from?

It's not specifically referring to the bovine animal cow, but actually the acronym COW, which means Communities Of [the] World, and refers to how technology (in computers and art) has changed so quickly over the years.

It may have also come from Patrick Smith's book called "A Land Remembered" where it mentions about wild "yellowhammer" cattle, that may be a local name for the Florida Cracker/Pineywoods/Scrub cattle that live[d] there.
