I’d like to do a “behind the scenes” look at Mathematical Games for an article. Martin [Gardner] did lots, but he avidly used a lot of help from hundreds of people. I’d like to write an article about the background help. If you ever assisted in one of Martin’s columns, I’d like to hear from you — a note about what you did. I’ll use these notes in my article.
A link from Pegg leads indirectly to a collection of weird and wonderful algorithmic paintings.
