      For building an Ultrasonic Brain Stimulation Chamber, of course.  The
   UBSC is a thing that looks like an small upside-down copper brewing kettle.
   To use it, you put it on your head, turn it on, and wait for enlightenment.
   I haven't tried it personally, but I hear it helps get ones mind out of the
   practice of seeing words and things in very narrowly-defined ways.  :)

It's neat!

By the way, I'm using ultrasonic to measure distance between the
sensor and an obstacle.  I can measure distance in range of such like
2cm to 2m with 1cm resolution, or 10cm to 10m with 5cm resolution.
