In the Swarovski Chamber of Wonder by Brian Eno, "55 Million Crystals by Brian Eno", checkpointmedia carried out the technical implementation of Eno's vision for Lumen London, mediapool and clear fog. What is unique about it is the fact that no visitor ever sees the same image or hears the same sound. By using images and sound sequences that ceaselessly shift into new configurations, Eno demonstrates the ephemeral nature of the moment and the true meaning of originality.
