LEMNISCATE CASCADE | 2022 | performance Life on Earth originated in an intricate dialogue between light and soft matter (liquids, colloids, polymers, foams, gels, liquid crystals, flesh and numerous other biological materials). In Lemniscate Cascade, a laser beam is reshaped during its passage through a light-sensitive liquid crystal – which is reciprocally transformed along the beam’s path. While stirring the liquid crystal, the laser light induces a state of lifelike self-organisation. Liquid crystal flows like a liquid, but is structured like a solid latticework. It has been broadly implemented as a medium for flat panel displays, yet the commonest example of this two-phase condition is DNA – the molecular foundation of living matter. To trace the liquid crystal’s light-propelled flow, hollow glass microspheres are suspended in the solution. These tiny lenses also serve to expand the liquid crystal’s sensitivity to brightness and color. During the laser beam’s self-shaping journey, it creates a projection that magnifies microscopic landscapes in the liquid’s depths.
