Gadgets to get diamond-like coating

Nokia has been experimenting with plastic casing coated with diamond-like material made from coal:
The material is more protective and grime resistant, as well as cheap and bio-degradable.

To make the material electric current is fed through coal graphite. This creates plasma, which is directed towards a plastic casing by high-voltage electrodes. The coal ions penetrate the surface and bond to form an amorphous, diamond-like coating less than 100 nanometres thick. The process works at room temperature, meaning even cheap plastics can be coated this way.

The coating is very tough, but also smooth to the touch. It is also conductive and therefore antistatic, so does not attract dirt easily. Furthermore, the surface reflects and diffracts light in a similar way to shiny metal. And, when the owner has grown tired of the gismo and binned it, the thin layer of coal will eventually degrade naturally.
