OK, this one just made me laugh. Equal parts whimsy and poltergeist?

The Flying Chairs Mobile is the latest design from Flensted Mobiles, a Danish company providing over "50 years of movement". The chair frames are made from cut and folded card. Ready-assembled, they simply need to be opened out before the mobile is hung up. Flat packed for easy shipping.
