Hotate

5,400 unicursal drawings.

pendulum : 53 swings /round
circle : -4.4 - 1.0 rounds

Hotate: This word is Japanese.
We write this word in Chinese character as "帆立".
It means scallop.
The moving pattern of this video is drawn by gradually increasing the rotational movement of the circle on the pendulum from -4.4 to 1 times / cycle. Negative numbers here mean reverse rotation (counterclockwise). At 2'26", it passes the point of zero rotation. You can see slightly different patterns for reverse rotation and forward rotation.
Around 1'50", we'll be able to see a scallop shell, so I made the title of this video Hotate.
