Actual Avatar Tree of Souls being built in London

If the 3-D effects of James Cameron's blockbuster didn't have you feeling close enough to all that Avatar action—and you happen to be in London this weekend—you're going to get your chance to plug into the film's sacred Tree of Souls for real, according to viewlondon.

As a promotional stunt to mark Avatar's Blu-ray and DVD release, Twentieth Century Fox Home Entertainment will be erecting a giant, interactive, replica Tree of Souls at Speakers' Corner in Hyde Park on Earth Day. Stephen Lang—who starred as Col. Miles Quaritch—will unveil the interactive exhibit, which will remain on display for three days between Saturday and Monday.

The Tree of Souls re-creation will be the largest fiber-optic installation in Europe, using 20 miles of fiber-optic branches. Sensors within the tree's trunk will change the color and intensity of its glow in response to movements made by visitors to the tree, who'll also be able to plug their iPods, MP3 players and phones into the tree, which will then glow and pulsate in time to the music being played.

Sadly, the press materials give no clue as to whether this particular Tree of Souls will be ponytail-ready. So if you drop by Speakers' Corner, be sure to let us know!
