Quattro Industries creates high-quality, hand-stitched soccer balls for age-group leagues, camps, and recreational organizations worldwide. They also create customized soccer balls for corporate and organizational promotion. When Quattro asked Vertex to create an e-commerce Web site to expand their overseas sales, Vertex developers decided to create a site that was playfully interactive. In the Store section, for example, the balls pop forward when moused over, bounce when selected, grow larger for a closeup view, and spin around at a touch.
