I went to Thin air, a new media art exhibition in London this weekend, which featured an excellent combination of light and sound and showcased the work of contemporary artists from around the world. The exhibition is a large-scale immersive exhibition that makes the element of light infinite.

The works that surprised me the most were those by the artists Kimchi and chips and Dutch artist Rosa Menkman, who used a combination of video projections, mirrors, and speakers to produce moving cross-beams of light and reflections to reveal volumetric light, the forms of which are materialised in the form of haze on the work.

After seeing the exhibition, I searched for other works by Kimchi and chips. On their website, I saw the work Halo, a bespoke installation in front of Somerset House in London, transforming sunlight into a visible and invisible form. The work consists of over 100 motorized mirrors arranged in a 15-metre track that changes direction as the sun moves, concentrating the sun’s rays in one place and using water mist as a medium to draw a large halo in mid-air. The artist created a mathematical model and developed a virtual simulation for each mirror. In order to achieve a clear halo of light, each mirror was set with a set of parameters to ensure its unique position, steering, axis offset, and polynomial correction parameters. Technology is used to create the infinite possibilities of art.
