     Nutella? Just goes to show the power of chocolate.

     You never know where the spark of creativity will come from.  The 19th 
century mathematician Hercule Poncaré solved the perplexing problem of the day 
while walking along the base of a cliff.  Something in the pattern of the rocks 
brought it all together.

     In the book "Zen and the Art of Motorcycle Maintenance", Robert Pirsig 
describes creativity as being a result of numerous subconcious thoughts in the 
subconcious coming together with a degree of "quality" that caused the idea to 
rise to the conscious.  Zen Buddhists call it the "place of ten thousand 

     I had such a thing happen many years ago while driving to a conference in 
Las Cruces.  I had stopped at the University of Arizona to copy some papers and 
scanned one in particular about a perplexing problem in analogue electronics.  
I was halfway across the San Simon Playa when the idea came as to how to solve 
it, an extension of two patents that I already held.  I pulled to the shoulder 
and spent a half hour sketching out the solution, with nothing but bare sand in 
every direction and two lanes of asphalt.  It became my fourth patent.
