Squarewave consists of 81 small reflective rotors which break incoming sunlight into numerous coloured beams of light. The rotors are suspended from a moving gimbal frame, consisting of four concentric squares, which keeps the rotors constantly moving.

Squarewave was commissioned by the department of applied mathematics of the University of Twente in 2014. Just before installation, the department had to move and the work was orphaned. In 2017, after a short exhibition and presentation at XPO, the DesignLab at the same university adopted the work – where it is now on permanent display.

The work was conceived, designed and constructed by Paul Klotz and Edwin Dertien.
