A new word recently coined is Tangleation. Simply put, “tangleation (tan-gle-a-tion), noun. A noticeable variation of an existing tangle.; inspired variations that are noticeably different but fundamentally same in basic approach; structurally based on the original tangle.”
Great and what a wonderful segue to introduce my Kardz tangle. Kardz is based on Crescent Moon and came into being about a year ago. It is one of my favorite tangles as you can see when perusing my Zentangles. If you can do Crescent Moon, you can do Kardz.
