Good tip, Maria.  I've really enjoyed the APE book--it does a great job
describing the prototyping process.  We've built a version of the pulleys
exhibit featured in the book, but l had forgotten that it also has a section
on the Bernouli Blower.  The "Creativity Killers" is one of my favorite
posters too.
