These were the so called “4D” lighting show back in last November for the 10 years anniversary of the RalphLauren.com. “4D” by itself was not the main topic. It was merely just the 3D images for the fashion show plus the scent of RL perfumes and colognes for the extra 1D. The exciting part was how they create the 3D effect by multiple projectors on a historical building exterior façade. The effects looked so real to a point that you would really think that the walls were falling apart during the show!
