The purpose of the program is to compare the visibility of the text when it is 
static versus when it flickers (so in some ways it's similar to signage).  
Therefore, I must make the text display switch back and forth between two 
displays with opposite black/white contrast to produce the flicker -- either a 
sudden swap or easing in/out are acceptable, as long as the switching back and 
forth can be repeated indefinitely at a given rate and does not block other GUI 
actions (a button press will be used to stop the animation). The smoothness of 
the font via anti-aliasing is not that important.

I hope that this is enough information to make the task more understandable.
