“Orange Socks” fills an entire wall of a gallery in Jerusalem, from floor to ceiling, and depicts the life-size silhouettes of 12 Chassidim, one of whom shows a flash of color. The artwork, by Rabbi Yitzchok Moully, is on display in the curated group show “Popthodox-Black Humor” until Nov. 16 as a part of the Third Jerusalem Biennale. (Art: Yitzchok Moully)
