PicoBlocks

PicoBlocks is a programming language designed specifically for programming your
PicoCricket Kit, a tiny computer designed for making artistic creations with lights, sound, music, and motion.
With PicoBlocks, you create programs by snapping graphical blocks together into a stack.

Based on research from the MIT Media Lab, PicoBlocks is highly intuitive and easy to use. To create programs, you simply snap together graphical blocks, much like LEGO bricks.
