The tour was designed by Willie Williams, who has worked on every U2 tour since 1982. Williams had been toying with ideas for 360-degree stadium staging for U2 for a number of years, and presented sketches of a four-legged design to the group near the end of their Vertigo Tour in 2006. The inspiration for the 'spaceship-on-four-legs' design, nicknamed 'the Claw', came from the landmark Theme Building at Los Angeles International Airport.

This concert film by Irish rock band U2 was shot on 25 October 2009 at the Rose Bowl in Pasadena, California, during the band's U2 360° Tour. The Rose Bowl concert featured a sold-out crowd of 97,014 people, breaking the US record for single concert attendance for one headline act. The U2 360° Tour was launched in support of the group's 2009 album No Line on the Horizon. The tour featured a 360-degree configuration, with the stage being placed closer to the center of the stadium's field than usual.

The great apes which include chimps, orangutans, gorillas and bonobos, seem to have rich emotional lives similar to our own. But just how smart are these animals? A new generation of investigators are converging on an explanation for why the non-human great apes never made the breakthrough into an accelerating human-style culture that builds on the achievements of previous generations.
