Love is in the Air (Flower Thrower), a stencil painting on the West Bank Barrier in Bethlehem, was created as part of the 9-piece "Santa's Ghetto" project. It is certainly one of the most famous of these works. It is the very representation of the poetry of his work as he denounces the wall in Gaza and affirms his support for the Palestinians.

In his book Wall & Piece (War and Spray, published in 2005), the artist recounts that when he was painting, a Palestinian told him that he was beautifying the wall. He took this as a compliment, to which the man replied that they did not want the wall to be beautiful and told him to go home.
