live U2 performance in nearly a decade and proved to be a hugely successful leg, with massive audiences attending these shows. On 9 March 2006, it was announced the final 10 shows in New Zealand, Australia, Japan, and Hawaii were postponed due to guitarist The Edge's 7 year old daughter Sian's diagnosis of leukaemia. (The initial start of the tour had been postponed for the same reason, prior to any tickets being sold.) On 20 July 2006, it was announced that they were rescheduled for November and December, with some adjustments and additions of dates. The fifth leg started on 7 November in Brisbane, Australia and concluded on 9 December 2006 at Aloha Stadium in Honolulu, Hawaii after thirteen shows. Stage design The Vertigo Tour's production was designed by architect Mark Fisher and stage and lighting designer Willie Williams. Key elements were an ellipse-shaped ramp on the floor connected to the stage, with some fans inside it and some outside it (similar to the heart-shaped ramp used on the previous Elevation Tour). The inside area of the ellipse came to be known as the "bomb shelter", in reference to the supporting album. In the North American shows, a set of seven retractable, see-through LED-based lighted bead curtains hung behind and to the side of the stage, showing abstract patterns, maps, moving figures, and occasionally text. The curtain design permitted concertgoers around the arena to have an excellent view of the curtains above the band and the images they displayed. The roll-drop LED screens were designed by Fisher using 360deg golf-ball pixels developed with Frederic Opsomer of Innovative Designs in Belgium. The spherical LED product joined the BARCO product line as the Mi-Sphere. The Vertigo Tour used 189 strings of these "MiSphere" LED balls suspended from custom truss, which allows the LED curtains to be rolled up. High above the center stage hung the MiSphere strings, each containing 64 spheres and totaling nine meters long. Dynamic, "moving" lights were also embedded in the stage and the B-stage ramp, as well. Four screens suspended above the stage showed close-ups of each member of the band, another element reused from the Elevation Tour. For the European, Latin American and Australian stadium shows, the bead curtains were replaced by an LED screen behind the band. The screen was assembled from BARCO O-Lite modules. The assembly of the screen was similar to the rigging used
