The idea is fine, but im struggling to see the point of those overlays. ie. The warped jigsaw peices, the greeny yellowy lines, and the hexagonal pattern. Simplicity is the height of sophistication; get rid of all the crap and it would look quite nice

/Edit - i've just noticed the dodgy edges too on the 2nd and 3rd closest pieces, and now I'm wondering if the overlays are trying to hide them
