Musical notes on a piano roll? Some of the squares are lines which could be equivalent to holding a note. I dunno, I'm no musician.
If it is musical notes,try to see if it fits the star spangled banner.
Okay, different idea. If all we are using are the bottom three images, there is a black and white color gradient in the colored squares. Three different ones. Superimpose them on each other or something like that?
So, looking at this one, the far right hand column. The bottom image has no squares. The second image has three squares and the third has two squares. All together they fill up that whole column. Dunno if that means anything though, but it does seem interesting.
If you superimpose them it looks like a blackout at least as far as I went with it.
Well, not exactly a black out because each image has different shading for the squares.
