Chindogu and Beyond
Chindogu: The art and discipline of unuseless product design.
unuseless: not exactly useless, because it does indeed serve a purpose, however, the importance of that purpose is grossly overshadowed by the absurdity of the solution.
This is a great example of an unuseless product. Is it really that convenient to be able to light two cigarettes at once? Who cares? It's a great idea. And why are the ladies so scantily clad? Who cares? It's a great idea.
