I recently came across Brian Eno's Oblique Strategies Cards as a means to breakdown creative blocks
These are a set of cards that offer a little creative inspiration when you need it most. The deck is the brainchild of musician and artist Brian Eno. The aim is to encourage lateral thinking through a random set of phases and instructions. . For example "Try faking it!", "What to increase? What to reduce?", and "Don't be afraid of things because they're easy to do".
The real beauty is that there are no "rules" for using them. If you feel like pulling one card, pull one; if you prefer four arranged in a square and want to place more significance on the lower left on, then go for it. The idea is to just set your mind off on a tangent, and who knows where it could lead.
They would be a great to draw on a new though or direction when you're stuck. Sometimes they will spark a discussion about something entirely unrelated, but I'll eventually circle back with fresh ideas. They're a little weird and very inspiring.
