PRIZM comes packed with 40 pre-loaded pictures that can be used in 8 out of the 15 built-in applications on the calculator including the graph, conics and geometry modes. The Prizm includes the world’s first Picture Plot function that enables users to plot graphs over curves and other familiar shapes in real life, such as the parabola of jets from a water fountain. The gadget has also a 3.7 inches color display, looking more like a smartphone than a regular calculator.
