This program displays an animation of Lorenz's famous
chaotic water wheel.  It also graphs the water wheel's
velocity vs. acceration vs. vertical-water-distribution
which becomes Lorenz's famous butterfly.

This file should run directly from your web browser 
upon clicking.  If it doesn't, then download it to your hard drive
and then double click it. If that also fails, then type
"java -cp WaterWheel.jar Space" at the dos command line to run
from the same directory that the jar file resides in.

(Note: if your computer incorrectly saves it as WaterWheel.zip,
then you must type "java -cp WaterWheel.zip Space" or rename it 
to a jar first.  Do not unzip it, that doesn't help anything.)

Water is entering at the top, and each bucket leaks
with a rate of 45.3 g/sec.  You can control all the
variables with the controls to the right.
In addition, the following keys do stuff.  You make the
keys work you must first highlight the approiate window.
You can highlight a window by clicking anywhere on it.

From Water wheel window:
  +,- change speed.
  mouse clicking a bucket selects that bucket allowing you
  to change the water level from controls.

From Graph window:
  +,- zoom in and out
  r clears
  d adds a dot
  arrow keys and a,s rotate through 3 dimensions
  g turns axis on/off
