This all reminds me of Brian Eno's "Oblique Strategies" cards.. something which I've used a few times.. good for creative thinking when faced with a block of some kind.

Is there a list of suggestions written on the cards?

It'd be interesting to see if playing the cards would actually increase business or not.
