The Prism of box kitesA series of intersecting ellipses, Phil McConnachie's elegant box won the Brunel Competition at Bristol in 2006. Steady as a rock in a wide range of winds, it tumbles and spins like the old star box kites when you tug on the line. Made of ripstop nylon with fiberglass spars, it springs open - no assembly required. 2'-6" x 1'-8", it flattens to 14" x 35" for transport. Wind range: 4 to 25 mph. Includes 200' of 20-lb. line on handle.
