Excerpt: Previous examples of simulacra -- religious images appearing on inanimate objects -- include a grilled cheese sandwich bearing the outline of the Madonna, which fetched $US28,000 on the internet for its Florida owner in 2004. She preserved the sandwich in a plastic container, after noticing a Virgin Mary shape on the bread. In 2005, hundreds of visitors left flowers, candles and rosaries in a Chicago underpass after salt residue created a stain resembling the Virgin Mary.
