I just came across this website (Art House Coop) that does worldwide collaborative art shows online. Anyone can upload images of their art on the day of the exhibition. They have done them on sketchbooks around the world, letters to home, things in jars, etc. There is an upcoming one where you take a photo of something you will eat from a certain time (midnight snacks in some countries, dinner in others.) I'm not sure exactly how the site keeps from crashing, but its pretty awesome and somehow benefits a world hunger organization. Related to ceramics because maybe someone in some country will eat off a wonderfully thrown plate? It could be you!
