Zinnia – A dizzying spring-driven kinetic sculpture

Watch more with these video collections:

Clayton Boyer’s Zinnia spring-driven kinetic sculpture is an optical treat as its two 24 inch (61 cm) diameter wheels change speed and direction. Watch as he briefly winds it for a dizzying quick spin demonstration.

On a full wind, it can run quietly for up to 40 minutes, creating a variety of shapes and patterns. Bonus: Boyer sells plans online, which allows makers to design their own wheel displays. Here’s a colorful variation by Bill Miller:
