Actually, if you're flickering 2 different shades of grey you end up with 4 
grey levels if you count the background.

Frame 1, using white:


Frame 2, using 50% gray:


Given a black background, the eye sees the first pixel as 75% grey (almost 
white), the second as 50% grey, the third as 25% grey amd the fourth as 
black.  Yeah, it'll be flickery but probably less so than the two-baby one.

I was thinking of trying low-res FMV using the playfield a while ago using 
this method, but it'd use too much ROM space to do anything cool.
