1999-11-19 -- Contraption

I had a dream that Mike F and I were in New York.  We were on the street and there were some guys setting up some kind of equipment in the middle of the street.  Little pastel panels with cables running between them casting a honeycomb pattern on the street.  At one end, a cable ran to a microphone on a stand.  A couple of speakers were connected near our end.  A woman stepped up to the microphone and said the number 5.  The speaker nearest to us began clicking.  Out of another speaker came the woman's voice.  It said "2.236" - the square root of 5!
