Carsten Höller creates what he calls “influential environments,” intended to create particular states of mind, like excitement and alteration, doubt and confusion, joy and fear. Instead of the artist’s vision being embodied in the artwork, his artworks often allow for self-experimentation producing particular experiences in the users. He has named the visitors of his exhibitions “his real working material.” Pill Clock (Blue and White Pills) (2015) marks time through the regular release of a single blue-and-white capsule every three seconds, the span often understood as the duration of the present moment. Suspended from the ceiling, the timed dispenser creates a growing pile of pills on the floor over the course of the exhibition. Visitors are invited to take a pill, if they wish, introducing a personal decision into the work’s steady, sculptural accumulation.
