"This volume surveys the key histories, theories and practice of artists, musicians, filmmakers, designers, architects, and technologists that have worked and continue to work with visual material in real-time. Covering a wide historical period from Pythagoras' mathematics of music and colour in ancient Greece, to Castel's ocular harpsichord in the 18th Century, to the visual music of the mid-20th Century, to the liquid light shows of the 1960s, and finally to the virtual reality and projection mapping of present moment, Live Visuals is both an over-arching history of real-time visuals and audio-visual art, and also a crucial source for understanding the various theories about audio-visual synchronization. With the inclusion of an overview of various forms of contemporary practice in Live Visuals culture - from VJing, immersive environments, architecture to design - Live Visuals also presents the key ideas of practitioners who work with the visual in a live context. This book will appeal a wide range of scholars, students, artists, designers, and enthusiasts. It will particularly interest VJs, DJs, electronic musicians, filmmakers, interaction designers, and technologists"--
