A gadget is not necessarily electronic. It can also be paper, metal, wood. The important thing is that the construction elements used to give utility greater than their basic use. The paper and the glue used in Landmine Stickers, for example, designed to raise awareness among passers-by.
The designer who did it respond to a request from UNICEF for a gadget capable of making people aware of the problem of landmines. Said than done. The sticker is a kind of wheel-shaped mine consists of two fronts: first, the design of a mine and the other the color of the floor on which should be supported.
The passer-by, not noticing the adhesive camouflaged, it tramples on the shoe. When he goes to check what has been trampled on, he realizes the wheel and realizes that if this had been a mine would have been seriously injured. A simple and effective message.
