Interface ecology is an emerging metadisciplinary approach, in which the creation of rich interactive experiences spans n disciplines --- such as computer graphics, mathematics, gaming, visual art, performance, and cultural theory. Interfaces extend beyond interactive artifacts, activities, and social spaces, forming intricate ecosystems. Interfaces are the catalytic border zones where systems of representation meet, mix, and recombine. Through this recombination, interface ecosystems generate fundamental innovations of form, experience, knowledge, and technology. This panel brings together a diverse range of practitioners who work from concept to experience not in terms of a particular discipline, métier, or medium but with a practice that interconnects multiple systems, forming a whole.
