Got some good suggestions on the pastry “bat signal” overnight. Most folks seemed to think that either a doughnut, a chocolate chip cookie or a raw egg would show up the best when projected onto a cloud. Pieces of pie, layer cake or single cupcakes were also good ideas. The most unusual one came from reader Suzanne, who’s apparently been brought to the edge by pastry projects on more than one occasion. Her suggestion: The Scream by Edvard Munch. Despite the emotional damage it would do to small children, I have to admit that would look pretty cool on a cloud. Thanks to everyone who contributed!
