I had one picture badly done this way, and I still think (I took that picture three years ago) that it could be use for a lot of purposes and with many results to be experimented.
"Multiplicity is the act of placing the same person a few times in the same photo"
Everybody talks about the looks of people like Madonna, Lady Gaga, Rihana, etc.. By I just found these pictures of the Italian singer Mina thanks to my last.fm, and she ranges from photos that are like Italian Renaissance and go as far as 80's deep deep looks, and I freaked out!!! Also her tendency is to look kind of "from the Dark side" so it adds some mystery, she could have been basically anyones muse, especially within Dadaists and Surrealist...
