From the publisher:

"Heliostat: Wim Botha brings together key works in the South African artist’s career spanning two decades and is organised around the idea of refraction. Refraction, as understood in optics, is the transformation of light, the increasing or decreasing of its wavelengths, as it passes through a material, such as glass or a prism. We perceive this change in wavelengths as either the splitting of light into its visible spectrum, a rainbow, or the bending or distortion of an object, as in a glass of water."
