Tarot cards can be fun and artistic — and as a character in Samuel Delany's classic sf novel Nova says, they can also provide an out-of-the-box input to better thinking about a situation. "Osho", aka "Rajneesh" (1931-1990), was an Indian guru/philosopher, and a nontraditional tarot deck called the "Osho Zen Tarot" is associated with him.
The Osho cards are, however, rather different from the "classic" system. Various conversions and translations exist. From kathryn.mnsi.net, with links to descriptions and images:
