"Halo" by studio Kimchi and Chips is a public installation of 99 robotic mirrors and a mist machine that resides in London, UK. However, the crucial element that completes the piece is the ever-changing sunlight throughout the course of the day. The mirrors follow the direction of the sun (like sunflowers), and the reflection of the light beams into the projected mist, ultimately creating a halo-like form - a form which "exists between the material and immaterial". It utilizes Bayesian inference machine learning in collaboration with unpredictable weather and natural forces to create a dynamic and ephemeral experience.
I find this installation particularly interesting because of how it is a superimposition of different timescales. Each moment is one different than the last, and reflective and reliant on the dynamic and independence of the sun, wind, and solar energy of the natural world. There is such an amazing juxtaposition and harmony of having such a robotic, machine like man-made structure with fine programming technology dance to the rhythms of nature.
