Apple's storefront design symmetry

Apple is known for its attention to detail, even in the smallest of things, and here's another example. ifoapplestore points to Apple's newly constructed 4th Street Store in Berkeley, California which is constructed to be symmetrical and aligned. The 76 centimeter stone tiles within the store are the focal point of this design. Both the store's windows panels and the sidewalk tiles outside the store are a multiple of this 76 cm dimension. It's a subtle design element that is pleasing to the eyes and may help draw traffic into the new retail store.
