When U2 started its worldwide tour on September 9, 2009 at Soldiers Field in Chicago, cheap airline tickets international it performed with a new giant screen backdrop cheap airline tickets international that changes size and shape during gigs. It is made of stainless steel, aircraft aluminum, and 888 LED screens with 500,000 pixels. Images can be projected across a screen area of 3,800 sq. ft. weighing 120,000 lbs. The expanding video screen provides a 360 concert view for fans. It is reported that every seat in U2 tour s 75,000+ seat stadiums will have an unobstructed view of the show.
The expanding video screen s development is based on designer Chuck Hoberman s patented Iris Structure that was the foundation for the Iris Dome at the Museum of Modern Art in New York City, the Iris Dome at the World s Fair in Hanover, Germany, and the Olympic Arch in Salt Lake City, Utah.
Hoberman developed an initial CAD model using SolidWorks software to determine information about component weights, sizes, and movement characteristics. Designers at Buro Happold created a structural model of the screen capturing mechanical connections and support details. As the work progressed, mechanical cheap airline tickets international details were shared with video screen designers and fabricator Innovative Design for their manufacturing input.
Mechanical design began in December 2008 and manufacturing was completed in May 2009. Due to a tight schedule, no scale models were produced. The screen progressed from CAD models to a full-scale, final version. The equipment can withstand high winds and harsh weather. The screen is durable to last an 18-month tour and can be assembled and disassembled in less than eight hours.
