Yes, I left that part out.  You need water, too, to make the
bamboo and sand computer.  Gravity and sand alone don't move
far and fast enough.  Water, sand and gravity - whew, that
could double the clock speed from 0.0002 Hz!  Ah, but I see
a snarky hand reaching up, asking "Why do you need the sand 
at all?" and I say "Persistence of memory!"
