I recently came across an article discussing edible art. Art shall not be constrained by formats. There are works of arts with food as their medium. The article features 10 food-focused museums and festivals around the world. For example, one example featured is the Arches of Bread Festival in Italy, where every Easter, a small Sicilian town builds a stunning cathedral out of bread.
