Hylozoic Ground, a Canadian art installation that was exhibited at the Venice Biennale, sounds like a really lovely, immersive environment. One warning: if you're the sort of person who's allergic to obscure, overwrought "artist's statements," the site may frustrate you — it took me about 50 clicks before I found a screen that actually stated, in simple text, what the installation was. Which is a pity, because it's pretty cool and I can't think of a single reason not to tell people about it. For your convenience, I've pasted it here for you:
Tens of thousands of lightweight digitally-fabricated components are fitted with microprocessors and proximity sensors that react to human presence. This responsive environment functions like a giant lung that breathes in and out around its occupants. Arrays of touch sensors and shape-memory alloy actuators (a type of non-motorized kinetic mechanism) create waves of empathic motion, luring visitors into the eerie shimmering depths of a mythical landscape, a fragile forest of light.
