Coloco unas líneas de esta nota de CNET sobre la tecnología detrás de la presentación, más específicamente sobre la pantalla expandible.
"The video screen is the first LED screen to be based on a geometric system that allows it to expand in two directions simultaneously," U2 360 architect Mark Fisher told CNET News in an e-mail interview. "Video screens are normally flat panels that track like closet doors, or slatted panels that roll up like garage doors. The 360 degree screen uses a scissor-like motion to expand in two directions. It starts as a solid elliptical ring approximately 20 feet deep, and transforms into form a cone-shaped mesh 60 feet tall."
Alucinante.
Sin más preámbulo y para los que no lo vieron, U2 en vivo, las dos horas y pico completas. Via el canal oficial de la banda.
