between 1 and 1.5 g. Once the barrel has attained full speed, the floor is retracted, leaving the riders stuck to the wall of the drum. At the end of the ride cycle, the drum slows down and gravity takes over. The riders slide down the wall slowly. Although Hoffmeister was the designer, most Rotors were constructed under licence. The first Luna Park Rotor was built by Ted Hopkins in 1951. Three Rotors were built in Australia based on Hoffmeister's design. All had been demolished or destroyed by the 1980s, although a slightly redesigned Rotor was rebuilt for Luna Park Sydney in 1995, which is still in operation. Coney Island (also Funnyland) One of the original 1935 buildings of Luna Park, Coney Island is believed to have been erected firstly at Luna Park, Glenelg, although this has not been substantiated. It is a rectangular building with the longest side running east–west. It has a corrugated iron hip roof with its external walls forming parapet walls around each side. The basic structure of Coney Island is virtually identical to that of the Crystal Palace. It is similar in width but slightly shorter, having twelve bays. Internally the steelwork of the main structure is concealed by mural panels or decorated motifs which were physically conserved during 1994. The roof purlins and sheeting are exposed. The industrial light fittings are suspended from the roof. The open space contains large and small fun devices, giant slides 1–4, joy wheel, turkey trot and barrels of fun. Crystal Palace (also Dodgem Building) The Crystal Palace is located adjacent to the site of the approach tracks and locomotive depot of the original Milsons Point Railway Station (1893 10 1924). The essential form of the Crystal Palace is a large rectangular thirteen-bay steel-framed structure, two storeys in height with a hip roof behind extended walls. The end bays are framed with heavy Oregon members and the roof ends above them are gabled hips with louvered ventilation in the gables. The exteriors were originally symmetrical, the two long elevations having emphatic central elements and end pavilions. Parapets conceal the main roof; these are crenulated except for the tower motifs where chamfered blocks of timber, imitating machicolation, have been planted on. The cladding, once predominantly asbestos cement, has been replaced in the early 1990s works with fibre-cement. The centre of the east or Midway entrance elevation has a steep hipped
