I can attest to Cliff's prior recognition of the Kaline variant. After he posted it I told him I was looking for one and he pointed out he had sent me one quite awhile back ( no charge by the way). I looked in my set and there it was. It is depressing getting old.
It is not the first variant Cliff has sent me without charge. There have been several.
And, I appreciate it when folks post variants here, even if they might have shown up elsewhere, because it is valuable having one thread where you can search for examples.
Darren does have a lot of great variations listed in his BST thread. Definitely worth a look
