After the release of the cover of "artpop", many people find that the reflection in the "blue ball" Jeff Koons as an error, but it is not an error (this looking or searching for 'koons ball' can understand). If you give Zoom the image in UHQ (see here: gagaimages.org/... 20cover/001.jpg%) see that in truth, the reflection is as if from inside a museum room (although being in a studio), where several people are watching the sculpture (which in this case is Gaga). All the reflection were strategically placed there as observers. People who appear there, representing all of us who saw the cover, the audience, who will appreciate or judge art. 'One second I'm a Koons, then suddenly the Koons is me!' RDT
