The Luminarie De Cagna is an imposing cathedral-like structure that was recently on display at the 2012 Light Festival in Ghent, Belgium. The festival was host to almost 30 exhibitions including plenty of 3D projection mapping, fields of luminous flowers, and a glowing phone booth aquarium, however with 55,000 LEDs and towering 28 meters high the Luminarie De Cagna seems to have stolen the show.
