Unfurling throughout the soaring dome of Vienna’s Karlskirche is a monumental neon squiggle sculpture and one of the largest works Cerith Wyn Evans has ever created. Spanning more than 80 feet tall and consisting of luminous tubes stretching 2,300 feet in length, the sculpture is the latest iteration of the Karlskirche Contemporary Arts program that aims to bring site-specific artwork to the Baroque church’s ornate interior. As the title suggests, the seemingly tangled tubes evoke imagery reminiscent of musical stores, scientific diagrams, or architectural plans depending on the viewer’s perspective.
