Getting lost in a forest of trees sounds like a lot of fun but then you realise things like bugs and wildlife and poison ivy exist. Not so fun anymore! What's guaranteed to be fun is to trap yourself in a cube of floating lights -- 8064 LEDs to be exact.
Called "Submergence" and created by a group of artists known as Squidsoup, the installation would surely bend your senses backwards by squishing your eyeballs with lights. The lights actually respond to movement through motion sensors, so you're definitely guaranteed a mind trip. Submergence is on display at Gallery ROM for Art and Architecture in Oslo, Norway.
