a mess of paper scraps hangs in a pink room; turn it, and from one exact view they snap into a picture that looks back at you, four times, the last a skull

Each scrap is hung at its own depth and only lines up from one seat. Hans Holbein did this in The Ambassadors (1533): the long smear between the two men's feet is a skull, and the National Gallery says it can only be seen properly from close to the painting's lower right. It is called anamorphosis.

Holbein hid a skull like this in a painting in 1533. It shows from one spot only.
