Braids

Fingerloop braid

Fingerloop braiding is a technique of making sturdy and decorative cords from threads. It is a type of braiding known as loop manipulation. The braid is made from loops of thread, attached at a central point, and the loops placed over the fingers and interlaced in different ways. In Europe it originated in the Middle Ages, and excavations from London have produced numerous examples in silk from between the second half of the 12th century and first half of the 15th. From the 15th century onwards, various directions and recipes for different fingerloop braid techniques began to appear in books and in print. A related technique, which involved the loops being placed over the hand or fingers, is the Japanese style. This technique arose in the 7th Century, and were used through the Middle Ages to the 19th century, for uses such as tying armour. (Wikipedia).

Teardrop linkage, in Lego

A tweet by @ChocoLinkage (https://twitter.com/ChocoLinkage/status/1174513390514921473) showed a teardrop shape being drawn by a mechanical linkage. I've tried to recreate it in Lego. Only one half works because it is difficult to avoid parts having to pass through each other.
