Yes, I know it's a no-no, but the psychology lab I work in needs the 
ability to alternate between two pictures on a mac screen at speeds 
up to 60 switches a second.

Working from Lightspeed Pascal, I would like the ability to initalize 
the alternative video page, put a bitmap on it, and then switch back 
and forth between the two pages.  I need to control this switch with
the tickcount variable for standardization.

Since our lab runs with a Mac Plus, we won't ever have any problems
with compatibility (at least with this experiment).

If anyone in Net-Land holds the key to rapid video page switching,
please share the wealth.
