From his website, Beeck describes Vulcania:
The dense foliage of exotic plants reaches to the sky, enveloping you and the sounds of falling water. Light from a glowing lagoon plays across the surfaces of this whimsical, fantasy oasis, vibrating with a new energy. Then you see it: Captain Nemo’s Nautilus, reborn out of the imagination of Burning Man, has returned to its island home. The creative wonder it discovered on the Playa has infused the landscape and now radiates from all the botanical, sculptural, and exotic treasures that Captain Nemo has collected from his adventures around the world.
The Nautilus is a land submarine, built by Christopher Bently, Sean Orlando and Five Ton Crane (an artistic collective from Oakland). It has a top speed of 13MPH and the chassis is actually a tow tractor used for moving aeroplanes.
