Big crush on this project by the Pneuhaus collective A « simple » inflatable structure, kind of Bibendum tent. The inflatable modules are double-walled, on the outside the plastic film used is opaque with a lens in the middle of the module, and on the inside, the lining is translucent so it becomes a projection screen of the image created by the fisheye lens. Then you can have a kaleidoscope movie of everything that happens outside the tent ! And I leave you to imagine if you smoke a joint… This principle could be applied to many applications, which makes it particularly exciting.
