Polar Rainbow, by the artist Kristaps Ancāns, is an Augmented Reality sculpture of a virtual double rainbow, which connects the North and South poles where rainbows don’t exist. The Polar Rainbow is rotated around the globe and finds temporary destinations where it is necessary to intervene. It connects us across actual time and space—signifying new beginnings, evolution and support as well as indicating togetherness and equality so that we never lose our joy and inspiration.
