Top 10 Guerrilla Artists

Graffiti-ing for Change
The barrier that separates Israel and the West Bank has become a controversial symbol of the centuries-old rift between the region's Jewish and Arab communities, but thanks to a trio of Dutch and Palestinian activists, it has become a canvas as well. In 2007, Faris Arouri, Yousef Nijim and Raji Najam launched SendAMessage.nl, a website that allows visitors to submit messages that the group will spray-paint on the wall for $40 a pop. (Words of hate or anti-Semitism are not allowed). So far, some 900 tidings have been added, including a 1.6-mile-long message by a South African anti-Apartheid activist and a falafel recipe.
