Interesting trailer below (note the 20th century fox is mirrored and whatnot), capped the checkerboard naturally (and cracked/fractured mirror image pulled from an image online). I have not yet seen this one but will view it with great interest.
Speaking of checkerboards, they are also all over the puppet programming movie Dead Silence (synchs up/same programming as this one) but I cannot find any better checkerboard images (there are) than this one. Unlike Mirrors, I have seen this one a while ago on Sky and is loaded with all the standard themes. This is from the creator of Saw (note the dummy's dissociative spiral pattern on each cheek), ALL (literally) these types of horror movies are designed to effect your mind (put you in a psychologically traumatized state [even if they don't realise/feel it consciously] where you are more easily controlled/influenced). Note that the trailer starts with a girl looking into a mirror. Note how the "crazy lady" refers to her dolls as her children, also note the shattered glass scene as they shoot the dolls.
