Here's another possibility...
[History first] A number of years ago I got involved in a project of which a part was to lead a team in coming up with "creative" solutions to various problems. After doing some research I came upon a couple books and an associated tool that I thought were
outstanding. All are by Roger van Oech.
* A Whack in the Seat of the Pants
* A Kick in the Seat of the Pants
* Creative Whack Pack
Your post inspired me to take a look to see if these resources might be applicable to "artistic" creativity as well as "business / procedural" creativity.
Short answer:
YES, definitely.
Since it's been awhile since some of these were published, they're available CHEAP. Note, there's been a couple editions of these published, older = cheaper, but content-wise probably very similar.

If it was me I'd opt to spend a few bucks for the "Whack Pack." It's quite good and portable. Easy to use and immediate.
The books are an enjoyable and entertaining read. Cleverly illustrated, too. Not a whole bunch of dry, theoretical B.S.
HTH...
