michael murphy's sculpture "tension" received critical acclaim and was featured in "time"'s year-end edition that featured the most prominent obama artworks. murphy used 1000 feet of high tension steel wire to create a profile portrait of obama. "obama's image pops out of the sculpture only if viewers stand at a precise location; otherwise, they see only a mess of wire." the portrait was displayed as the prominent piece of the manifest hope: dc art show, curated by shepard fairey.
