Download the files in this folder to run the "bubbles" sample OpenGL
program.  You need bubbles.exe, isu.raw, and freeglut.dll.  The program 
is compiled to run on Windows.  You can also compile it to run on the 
x** machines in room A-015 - see ../bubbles.cpp.

Then to use the program, you can ...
  * left mouse click: fire laser
  * right mouse click and drag: rotate view of the world
  * + and -: move forward/backward in the world
  * left/right/up/down arrows: move in the world
  * r: reset your position in the world to what it was when the 
       program started
  * 2: add more bubbles to the screen, (roughly double)
  * after "popping" all the bubbles, twice as many new ones will appear
  * bubbles automatically disappear when they get too far away and 
    reappear closer again.
