ScratchBit is an effort to enable children to create more seamlessly in both the physical and digital world by creating a dedicated physical interface for the Scratch programming language and environment. Designed to be rugged, low cost, and highly composable, the ScratchBit allows children to take the materials around them—such as cardboard, clothes, skateboards, and trees—and transform them into inputs to their digital creations on Scratch. Unlike the Makey Makey which was designed to make these connections electronically, the ScratchBit is designed to create these connections through motion and mechanism.
