After a quick check of the calendar, no it's not April's Fools day. Nissan has actually unveiled the world's first self-healing iPhone case.

Built for the iPhone 4 / 4S, the case is constructed from ABS plastic and features Nissan's scratch shield paint which can mend small scratches in as little as an hour (up to a week for large scratches). As the company explains, the case's exterior "is made from polyrotaxane, which means that when damage occurs to the coating in the form of a fine scratch, the chemical structure is able to react to change back to its original shape and fill the gap - 'healing' the blemish."

Besides having a certain gee-whiz factor, the case has a "tactile gel-like" feel that provides better grip than traditional cases.

Nissan is currently testing the cases and is considering production if there is enough demand.
