DemoA Help

Probably, not much help is needed for this control panel.  However a few points
are worth mentioning:

   --- most of the demos are randomized, so they are different every time you
       run them

   --- most of the demos, but not all, work in anaglyph stereo mode.  the ones
       that don't are mostly on the DemoB panel

   --- the `Never ending exhibitions' are just that.  After clicking on these
       buttons, KnotPlot will go into fullscreen mode and run forever until you
       press the ESC button.  


   --- some demos have their own little help pages.  over time the number that 
       have will increase.   update your KnotPlot frequently.

   --- Many of the demos ask you to press a specific function key F1 thru F12.
       On MacOSX machines, some of these function keys do other things.  I think
       you have to press APPLEKEY-F12 to get what KnotPlot sees as an F12 key 
       press (for example).  I'm sure MacOSX users know about this already.
