My kid and I made it out to the Architects of Air exhibit in Austin. The first picture, taken from the outside, show what the "tents" are built like. The silver areas are densely coated and minimal light shines through them. The colored areas are translucent and light streams through them, creating geometric panels as seen from the inside. You can read more about this traveling exhibit at their website.Pictures from inside the luminaries. This first room, "The Airlock" was the simplest of all.
