IODC 2021 illumination design problem: the curse of Prince Lambert

For the 5th time, the International Optical Design Conference (IODC) included an Illumination Design contest. This year, the contest involved designing the optics to reverse a magical curse that was placed on Prince Lambert. The goal of the problem was to maximize the flux when a specified ray source was traced back through optics that had to fit within a 220 mm by 220 mm by 220 mm box. The winning solution was provided by Jake Jacobsen and the winning student solution by Shohreh Shadalou.
