Scratch takes its name from a technique used by disk jockeys called scratching, where
vinyl records are clipped together and manipulated on a turntable to produce different
sound effects and music. Like scratching, Scratch lets users combine blocks and mix

different media (including graphics and sound) in creative ways by creating and remixing
projects like video games, animations, music, and simulations.
