Egg cup creators are always looking for new sources of inspiration, and it could be that sometimes they don't look very far. What should they? Doesn't the egg itself have a marvelous shape, as well as unforgettable colours? In this selection we can see egg cups inspired more or less directly in different types of eggs or egg's states: hard-boiled, fried, as an eggshell or as a broken eggshell, for instance. I haven't found yet any egg cups imitating scrambled eggs, or maybe I found them but didn't recognise them. The important thing to know is that egg shaped egg cups produce what art critics love to call the mise-en-abîme effect: you'll eat your egg in an egg.
