Was I the only one who saw graph paper? I like GeneralE's pixel theory - far more appropriate to the current medium. (I'm old school. I remember graph paper. I loved graph paper.)
I like the pun, though to be honest, I probably would not have given this a high vote either. However, I'd be disappointed if I saw high wow factor, cliched DPC fare coming from you. You stay true to form in both your comments given and your own entries. Good going.
Excellent example/illustration of the concept of the bitmapped image being comprised of pixels.
It might be interesting to select inside each of the squares and average the color values to see what it would look like if each square in the screen was really a single pixel.
