According to New Scientist, Swiss scientists are experimenting with small, low cost processors to be embedded in furniture to ensure you construct it the right way.
An alarming fact has come out of their research – they found, “44 different paths that someone working without the instructions can take to fit the pieces of an IKEA wardrobe together. But only eight of these result in a safe construction. Other paths lead to something that looks stable, but is not, or come to a dead end.” Now I am really frightened lest the contents of my flat (almost all self-constructed IKEA stuff) collapse on top of me!
