ART HACK

I am collecting information for two projects, both exploring the creative process. But before I can move forward, I need your help.
Please contribute:

1.) Advice. How might one break a creative block? Is it possible to catalyze inspiration? How?

2.) A short (one or two sentence) description of a project that has gone unfulfilled. Spare art ideas, please! The more the better. Feel free to include drawings.
