Oblique Strategies are cards containing cryptic phrases and expressions to promote creativity created by Brian Eno and Peter Schmidt in 1975. Most famously used by David Bowie whilst recording his Heroes album [alongside Burroughsian cut-up fragmentation of lyrics].
A toy with a similar objective is the Magic 8-Ball. A much more ancient and involved variant is found in the Trigrams of the I Ching. Of course with all such supposed divination methods one has to use any seemingly prophesied outcome as merely a starting point for one’s own intuition, else one is apt to fall into the trap of William Shatner in the Nick of Time episode of The Twilight Zone  when confronting a mystic seer fortune telling machine in a roadside cafe.
