Fritz Maierhofer / Sushi Design (Naulila Luis)

Vienna's Fritz Maierhofer models these rings on his computer before forming them out of Corian, an acrylic polymer material commonly used on countertops. Of course, they can also be made by boiling a few hundred Cosby sweaters down to their essence, then pouring into a mold.
