Fly Me to The Moon, in Graffiti. Fly Me to the Moon [wiki] is a fantastic song written by Bart Howard (and sung by many, many famous singers). Here are its lyrics ... in graffiti!
Yesterday, Nico woke up in his flat in Split Croatia. On his closet door was a map created by his girlfriend, Andrea. The map showed different places for Nico to look as his took his usual route from his apartment to the academy where he studies.
What Nico found was an elaborate love poem done on the streets of Split by Andrea. She had put up stencils, paint, aerosol, collage wheat pastes etc. with last piece reading.... "i love you".
