On your left is a simulation of the Caterwaul, a wailing wall for Second Life and other virtual lands.
Should you choose to visit the virtual Caterwaul, visit it in Second Life at Ars Virtua.
Should you choose to visit the real life Caterwaul, visit it at the Huret & Spector Gallery, 10 Boylston Place, 6th Floor, Emerson College, Boston, Massachusetts.
Or click on this audio stream link to vicariously eavesdrop the wailing. Below is a slowly updating photo of the space in front of the real life Caterwaul.
