The Mona Lisa on Toast by Tadhiko Okawa recreated Da Vinci's Mona Lisa ... from pieces of burnt toast. Okawa creates these edible works by etching the picture on aluminum foil, wrapping each piece of toast in a section of foil, cuting out the design, then toasting it in a horizontal toaster.
Also at Ripley's...President Obama...in Gumballs. Maybe later.
