I learnt a new signifier today, "Droste effect", from Ray Girvan at JSBlog (Last visible Droste). The signified is familiar enough (an image containing a copy of itself, to several levels), but I didn't know the name. By coincidence, however, today's Today image (copied here, left – from another visit to Crimes of passion) contained an example of the effect.
[Addendum, : Ray points out to me that he has blogged the topic twice before (Escher image analysed and Droste effect revisited) by name. After a brief hope that I might have just missed those posts, I had to admit to myselof that I'd simply let them leak though the holes in my memory...]
