Stacked Balls ala Selfridges in Birmingham
At first blush, this looks like a hexagonal pattern, but, as shown above, the pre-baked hexagon is not going to give you the nice even and alternating stacked distribution that this building exhibits. It can actually be decomposed into a brick pattern. The default behavior of the 1/2 step brick gives you a brick that is twice as long as it is tall. However, if you set the number of gridlines to be a U value of 2x' and V to be x', you get a square, alternating pattern.
