This looks very promising indeed: American artist James Turrell has been working with the medium of light since the 1960s, picking up accolade after accolade, and even opening his own museum in Argentina. He's best known for ongoing work, Roden Crater - fashioned from an extinct volcano, it's a naked-eye observatory out in the Arizona dessert. Other pieces include enclosed apertures or 'skyspaces', as well as projections. More details as we get 'em, but definitely one for the diary.
