'' Pieces for Peace '' is a CITYarts project started in 2002 . As stated on the CITYarts website , this project " was designed to build bridges of international understanding by bringing together American youth and their peers from around the world to create drawings , paintings , and poems . " These works have been exhibited at the UN in New York City . As part of this project , the CITYarts Peace Wall in Harlem , a mosaic was installed in the Jacob H. Schiff Park at 138th St and Amsterdam Ave in New York . The mosaic design was created by artist/illustrator Peter Sís in collaboration with international youth , and was completed in 2005 . The project is currently undergoing restoration with artist Ricardo Arango . '' Forever Tall '' was a mural completed in 2001 , as a response to 9/11 , overlooking Cooper Square in the East Village of Manhattan . The mural depicted the skyline of Manhattan at night with the twin towers as two columns of flowers . The lead artists on this project were Hope Gangloff and Jason Search . The mural no longer exists as the wall was subsequently painted over to be used for advertising
