Hard to tell from this picture, but Apple was displaying giant iPads inside giant snowdomes. The display creators took the analogy a little further and had snow falling throughout the whole display, rather than just inside the dome.
I thought that was a very fun way to capture the viewer’s imagination. (And that appeared to be true for those inside the store, anyhow.)
It’s often helpful to take things out of context. That can greatly increase awareness of what you wanted to highlight.
