In commemoration of the 30 year anniversary of the Scientific American cover "Theory of Tiles"(January 1977), a question was posed: Can the cover art be modified such that the tiles become Spidrons.* Each individual tile in the resulting pattern has the same area and obeys the same rules as the original tile created by Penrose & Conway. A copy has been sent to the authors, Science News and Scientific American.
