Ever feel like the pictures are moving?

This is not a question of philosophy. Yes, I do sometimes feel as if the world has a series of pictures moving by me... And never more strongly than in the breakfast cafe in the airport hotel in Hong Kong.

I finished my eggs and decided to look at the (IMHO overly modern & slick) decor. Fancy bottles of oil on glass racks above the buffet... I thought there was a picture across from me. Why is there now only half a picture? Could it somehow be moving?! Naw, that's just crazy talk. *Eyes travel up, note ceiling hangers, note circular track in the ceiling* It is moving!!!
