” The Eggbot is an open-source art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball size to that of a small grapefruit– roughly 1.25 to 4.25 inches in diameter (4 – 10 cm).

Not just eggs but golf balls, light bulbs, mini pumpkins, and even things like wine glasses– with a bit of work. ”
