For the 2005 relaunch of adidas tennis, we created a dynamic interface based entirely on the movements characterising tennis, particularly the curves found in the lob of the ball before a serve, the flattened sweep of a powerful swing and the bounce and bursts of energy embodying the sport. The entire site is built around a strict dynamic grid enabling vertical and horizontal mirroring of all layout elements revealing harmonic variations of the layout in repeated visits or activity.
