Chindogu — The Japanese Art of inventing useless stuff. A Chindogu cannot be for real use. A Chindogu must exist. Inherent in every Chindogu is the spirit of anarchy. Chindogu are tools for everyday life. Chindogu are not for sale. Humour must not be the sole reason for creating a Chindogu. Chindogu is not propoganda. Chindogu are never taboo. Chindogu cannot be patented. Chindogu are without prejudice.
