I love the black and white. I believe that this simple combination of colors can create a great effect on anything. The way these are organized are also very simple. It looks like a testing logo, or a loadng screen, and I think that these effects allow for a nice wallpaper, or background, or banner, or whatever someone can wish to use it for. However, because of this simplicity, it also appears to be over used, and could be a new design if other techniques were used. Overall, this is a good design though, and it will become my new background instantly!
