Boyner's holiday windows were designed as a template to be used at all the locations of Turkey's largest department store chain. The commission involved the design of multiple 2-meter-high snow globes containing stacks of prettily wrapped gifts that were constantly dusted with Styrofoam snow that looped through the globes via a specially designed fan system. At Boyner's main Istanbul store, a larger-than-life 11 m glass showcase was also converted into a giant snow globe, designed and built based on the Venturi effect.
