The ongoing explorations of the natural world and other phenomenon by Olafur Eliasson and his able team of artists and collaborators delight the senses and tickle the mind. Often, these take the form of installations or immersive sculptural experiences. Eliasson utilizes technology, geometry, science, hydrology, and much more to produce the art. Environment is a primary subject of his, and his works have an activist intent even if sometimes they are so seductive that the viewers become entranced by their special characteristics.
