The Rolling Reels Circus — Il Circo dei Rocchetti Rotolanti — is one of my early paper automata. The idea is very simple: a set of reels rolls and moves through a simple play of balance and gravity.
It was designed in 2005 as a playful object rather than a realistic model. The mechanism remains visible and deliberately elementary: the paper construction, the motion and the slightly absurd circus atmosphere are all part of the same little machine.
The model is intended to be printed, cut and assembled from cardstock. Once built, it works as a compact mechanical toy: a small paper performance activated by hand.
“This is the perfect thing to have at work for when I need a ‘mental health moment’.”
