Saber was already a fixture in the Los Angeles graffiti scene by 1997 when he completed the largest graffiti piece ever created. His piece on the sloping cement bank of the Los Angeles River was nearly the size of a professional football field, and took 97 gallons of paint and 35 nights to complete. In a famous photograph—taken by his father just after it was finished—Saber stands on the piece and appears as a tiny speck amid a giant blaze of color. It catapulted Saber to legend status in the graffiti world.

He began exhibiting in his fine art in 2002. His monograph, SABER: MAD SOCIETY, complete with stories of his graffiti misadventures, was released by Gingko Press in 2007 and is now in its second printing. In October 2010, Saber released a video in which the year's heated debate about health care was spray painted over the American flag. While some saw it as desecration, Saber advocated for health care reform in the video, revealing that he had epilepsy and was un-insurable. This work led Saber
to create a large group of American flag paintings called the Tarnished series.
