I think it might be fun to start up a collection of snake oil
cryptographic methods and cryptanalytic attacks against them. It
would be more fun for me than crossword puzzles, and educational for
all the would-be cryptographers.
One good candidate would be Enigma 2000, now available as Enigma 2000 Plus:

Unfortunately, there is little information available, but from what I
saw a few years ago, this is a polyalphabetic cipher with a large key.
From the web site: "Die Kombination aus der Vernam-Codierung
(One-Time-Pad) und des von T. Heidel zum Patent angemeldeten Verfahrens
macht eine "bis zu beweisbar sichere Dateiverschlüsselung" möglich."
Or, in English: "The combination of Vernam encoding (One-Time-Pad) and
the patent-pending approach by T. Heidel enables "up to provably secure
data encryption"."
Fun,
Stephan
