At the end of the documentary on the making of 'Elevation' on Disk 1 press 'Enter' when the 'Dreamchaser' logo appears at the top of the screen and you will be taken to a screen full of flashing cubes. Enter the code 1-9-7-6 to be taken to a further screen where if you select 'Bonocam_one' you will get a first person view of everything Bono sees as film from a camera on his glasses during the song Elevation.
