London-based street artist D*Face has created an artwork using skateboards, paint cans and an empty swimming pool in Southern California.   For the Ridiculous Pool Paint Attack project, the artist invited skate boarders to ride around the empty pool with paint cans attached to their board. As they rode, their boards released paint on to the pool's surface. This was no mean feat however. D*Face used technology such as transmitters, receivers, remote controls and signals that triggered a pressure-sensitive button to release the paint. The result was a colourful trail of interweaving lines behind, which has been documented in the above video. D*Face was inspired to execute this idea after witnessing his previous swimming pool art being torn and distorted by the linear motions of the skaters who rode through the pool, and wanted to recreate the pattern of lines created by their motion. For this project he drew together elements of street art, sport and technology. We look forward to seeing more collaborative projects like this, which explore and track the movement of people through spaces.
