From Gaza's colorful neighborhood to its underground theater, resistance is an art. Mohammed al-Saedi leads me through the densely populated Gaza City neighborhood of al-Zaitoun. Walls are painted in blues and pinks, with wooden shutters of purple and yellow. Plants are potted in colorful buckets at each corner. "Color and flowers give the human positive energy, relax him, and provide much-needed comfort to the soul, heart, and mind," says al-Saedi, a slender man of 57, wearing a paint-splattered shirt.
