All code was written in Cricket logo using Microworlds for WindowsNT. We ran into several obstacles in the process because our application pushes the limits of the Cricket logo system. A real-time music toy that responds dynamically to sensor input and infra-red is no small task even for the mighty Cricket. Stack overflows, an excess of variables, and excess program size still loom in the way of a few unimplemented features. We do, however, owe the great success we have had to Bakhtiar Mikhak and Fred Martin.
