Widely heralded as one of the most important artists of his generation, Olafur Eliasson merges art, science, and natural phenomena to create extraordinary multisensory experiences. Challenging the passive nature of traditional art viewing, he engages the observer as an active participant, using temperature, moisture, aroma, and light to generate physical sensations. Here he describes how his work Beauty (1993) engages viewers.
