Dust Storms

They are known by many names: Haboob, Simum, Black Blizzards. A solid wall of dust almost a mile high, moving whole sand dunes and bringing Biblical darkness to the huge areas of the world. Scorching hot winds (up to 40 degrees Celsius) blowing the sand around with hurricane speeds... What seems extreme to us is actually a common occurrence in Africa and the Middle East. The similar sand-saturated hurricane-speed storms over Mediterranian are called Sirocco, Yugo and Ghibli. The dust (or desert sand) particles become airborne and held in suspension, creating a moving front. The convection of cold air over the heated ground maintains the storm and keeps the dust rolling.

Playing in two dimensions is easy enough, but what truly separates the men from the boys? Maybe it’s when you give up your easel for a tool belt and get to work with a hammer and chisel. These amazing sculptors took their talents 3-D.
