Cocoon is a house shaped like a zeppelin in Australia. It sits propped up on the edge of a steep drop off, as if it's tempting people to make Hindenburg jokes. I'll resist the urge. [Designer Choice via Inhabitat]
Kinda sad that the first thing I think of when I heard "Cocoon" was this.
Ay, ay, ay,
I'm your little butterfly
Green, black and blue,
Make the colors in the sky
Couldn't find one without cheesy anime pictures :( but what else can I expect?
