Some cool new gadgets aren't sold in stores. The D*Face Spray Paint Skateboard Interface took a year to create and won't be found on the shelves of your local skate shop.

Let's break down the D*Face Spray Paint Skateboard Interface. D*Face is a London-based street artist. Spray paint and skateboards are self-evident. The interface part refers to a remote control system that can trigger paints cans attached to the underside of skateboards.

This technology could easily be used for less-than-noble purposes, but D*Face created and harnessed the devices in the name of art. The canvas was a skateboarding pool in Southern California. The pool had previously been a site for a D*Face project that covered it with piles of painted skulls.

According to a behind-the-scenes look in Concrete Disciples skateboarding magazine, the chosen spray paint was a very fast-drying enamel. The cans are strapped under the deck with Velcro and are controlled by wireless remote.

Different skaters took turns running through and looping around the bowl, leaving behind brightly-colored lines to mark their trails. The result looks like a massive concrete Spirograph gone wild. This adds a lot of visual spice to the usual gray surfaces that skateboarders roll on.
