We have covered plenty of plastic and wooden rolling ball kinetic sculptures here. The Factory is a kinetic rolling ball sculpture made of concrete. The balls roll through various elements, including a spring-like path. This rolling ball sculpture uses 5mm stainless steel balls.
The Factory weighs 3.14kg, which is to be expected considering what it is made of. 11 steel balls are included with it. It has a footprint of 20.5 x 16 x 11cm. MaterialImmaterial is selling this on Etsy.
