Awesome kid fort idea: king size duvet cover plus exhaust fan facing into duvet cover=awesome fort. Or use a king size bottom sheet over a queen size bed and face fan inwards. Great hot summer night idea for kiddos.
Take a psychedelic trip (without actually tripping out), and enjoy Verner Panton's Visiona the “Fantasy Landscape Room” foam rubber room exhibition he designed for the 1970 Cologne Furniture Fair. We'd love to see something like this at ICFF this year!
