Fred Eversley, a sculptor known for his otherworldly discs made of tinted resin, has died at the age of 83. Eversley, who had an engineering background, used a technique inspired by Isaac Newton to create his unique sculptures. His work focused on energy and the scientific concept of the parabola. Eversley's sculptures, which were often translucent and displayed vertically on pedestals, created optical effects and changed color depending on the light and viewer's movements. He was successful in winning public commissions and his work can be found in various locations, including Miami International Airport and Central Park.
