We describe a new style of MOOC designed to engage students with an immersive multimedia environment including text, images, video lectures, computer-based simulations, animations, and tutorials. Quantum Mechanics for Everyone is currently running on edX and has been successful by a number of different measures. Building on the pioneering work of many, it illustrates both how one can teach complex quantum phenomena to nonscientists and how one can develop high-quality interactive computer simulations that engage students and can be widely deployed.
