This project references the binary illustration in the "Introduction to Computer Science and Media Computation" chapter of the book "Introduction to Computing and Programming in Java: A Multimedia Approach" by Mark Guzdial and Barbara Ericson - the idea of doing a scratch project was to show students the basic base 2 binary number scheme without resorting to typing in code to get the idea. Scratch includes a number of math operators, and can be used to show how binary numbers work, even though there's no expiicit base two or exponent operator available in the base distribution of Scratch.
