I am teaching a short course on math (actually 'Fun with Math') to a group of junior high students. One of the things I plan to teach is cryptography. Does anyone know of a supplier for 'Secret' Decoder Rings - like the type that companies used to put in cereal boxes. I would like to buy a few for the kids to help illustrate coding/decoding the Caesar cypher. Please respond to: R. L. Platt cbosgd!cbscd5!rlp
