UK-based satellite TV station Sky Arts have created a pyramid on London's Primrose Hill to publicise their showing of Pink Floyd's Earl's Court 1994 performance of The Dark Side of The Moon on Sky Arts 1 in high definition.

The 5-metre high pyramid, shown to the right with the London skyline [click thumbnail], promotes the screening of Pulse: The Dark Side Of The Moon Live, which transmits on Sky Arts 1 and Sky Arts 1 HD today (Friday October 23rd) at 10am and 4pm.

The large 'prism' uses diffused LED lighting to create the album art's glowing effect. Lasers were installed behind the structure, a white laser emitting from the left hand side and coloured beams emitting from the right hand side, to re-create the image that appears on the famous Pink Floyd album cover.

UPDATE: The people behind this very impressive installation documented the creation, and the following video gives a whistle-stop guide to the construction, and a look at how it appeared on Primrose Hill:
