What a great effect

So I've always been fascinated by mirrors, especially when you have mirrors facing each other so it looks like you are looking to infinity.

Well some clever artist came up with this vertically stacked column of books that has a mirror for a ceiling and floor so that when you look into it you are in a never ending stack of books. When you put your head in there obviously a great deal of the space is taken up by your mug, but when you simply put your iPhone in there the effect is very cool.

Kudos to the artist.
