Lame? Perhaps. But there is a precedent....

Peter Reynolds writes on his site:

I have a promise to myself that I will make a mark in my journal each night, even if I am tired. I will try to jot a drawing, or a poem, or a word, or even a simple mark to just prove I was alive that day.

One night, when I was exhausted, I made a mark with a black felt-tipped marker and promptly fell asleep. When I awoke with a start an hour or two later, I noticed the little mark had mushroomed into one giant black dot.

I put the cap on the pen, put the book to one side and went back to sleep. When I awoke the next morning, I looked at the journal again and instead of seeing it as a mistake... I suddenly realized that perhaps this was one of the best ideas I had ever had.

I grabbed the pen and quickly jotted "The Dot" above the black dot and "by Peter H. Reynolds" below it. I had just created the cover to my new book.
