Planetariums have historically been venues that projected points of starlight on a curved ceiling, but with the advent of new technologies and software, digital "fulldome" theaters are rapidly expanding and converting planetarium domes into an immersive virtual social experience augmented by computer graphics and scientific visuals. Digital dome theaters extend educational and cultural programming beyond night-sky astronomy, including science shows both recorded and interactive, live entertainment events, and more. Their computer graphics content can range from scientific visualizations to interactive art.
