Berlin-based artist Sebastian Bieniek unfolds the story of a two-faced female in his series of photographs “doublefaced”. Using an eye pencil and lipstick, bieniek simply draws an image of a face onto the side of skin. The sketch includes only one eye: carefully placed hair hides the rest of the face from view, revealing one, moving eye of the model. Blue, brown, awake, and sleeping variations create portraits with unique expressions and an illustrative sensibility. The 22 photographs of the hybrid girl expose her daily routine – drinking coffee, traveling on the train, taking a shower, and smoking cigarettes – capturing the daily life of a female with two faces.

Miles Van Rensselaer using everything from glass and crystal to bronze and iron, from gold and silver to tooth and bone, from steel, copper and lead to wood, clay, feather and hair. He has been fortunate enough to work – and humbled by working – with and among talented artists from all over the world. His work is his homage to these people and their vanishing ways of life, his translation of their technique, imagery, idea of “primitive” art into modern Western materials.

Ra Paulette is an American cave sculptor based in New Mexico who digs into hillsides to sculpt elaborate artistic spaces inside mountains. Reviewer Martha Mendoza in the Los Angeles Times described the caves he created as shrines, as hallowed places, a “sanctuary for prayer and meditation” while others describe the caves as works of art. The caves are finished with “scallops, molded curves, smooth ledges, inlaid stones, narrow pods and crusty ledges”. His caves attract visitors worldwide.
