Emblazoned on a long, tall, concrete barrier in the midst of a rocky Middle Eastern landsc

ape is this spray-painted message: “Mirror, mirror on the wall. When will this senseless object fall?”

It’s one of more than 900 graffiti messages that have been spray-painted by Palestinians on the controversial wall that separates Israel and the West Bank.

The painters take orders through a Web site that lets customers get a message on the wall. For the equivalent of $40, a Palestinian will spray paint the message and send three digital photos of it.

Anything goes — marriage proposals, jokes, notes to friends — as long as it isn’t extremist, hate-filled, or pornographic, said Faris Arouri, one of the founders of the site.

“Trying to imagine a clear view between Palestine and Israel,” one reads.

“If all humans are equal, why do they have to live separated?” says another.

And another simply shouts: “Get along with each other!”
