Born out of the creative genius of Manchester artist collective the Ultimate Holding Company (UHC), ExtInked is a "social experiment". "Disparate communities are coming together, artists, tattooists and ecologists," explained UHC's Jai Redman. "I want to see them overlapping and interbreeding, sharing ideas and visions." The experiment involves a hundred people receiving tattoos of endangered species, from yesterday until this Sunday, in a bid to raise awareness of conservation issues.
