Oblique Strategies are a great way to keep your mind thinking outside the box. When you're working on a problem and you seem to be stuck, having an oblique strategy around to give you a fresh perspective on your problem can be helpful and fun.

Oblique Strategies were originally published as a set of index cards in 1975 by Brian Eno and Peter Schmidt.

This site is currently using third edition of the cards, however the publishers are currently on the fifth revision.
