“Big Air Package”

 "The 'Big Air Package', an indoor installation for the Gasometer Oberhausen, Germany, was conceived in 2010 and is on view from March 16 to December 30, 2013. 90 meters high, with a diameter of 50 meters and a volume of 177,000 cubic meters, the work of art is the largest ever inflated envelope without a skeleton."

I could imagine reclining back on a white sofa listening to the Beatles White Album in a white jump suit drinking milk in this strange environment!
