Oblique Strategies
Work at a different speed
From Wikipedia:
Oblique Strategies (subtitled over one hundred worthwhile dilemmas) is a set of published cards created by Brian Eno and Peter Schmidt first published in 1975, and is now in its fifth, open ended, edition. Prior to Oblique Strategies, Schmidt created "The Thoughts Behind the Thoughts" [1] in 1970, a similar collection of "55 sentences", in an edition of 100.
Each card contains a phrase or cryptic remark which can be used to break a deadlock or dilemma situation. Some are specific to music composition; others are more general.
