MCM Theater is a Java package that I developed in the early 2000. It provides an easy to use class library for an introductory Java programming course. I used it in a Mini Course for 8-th graders at The at Galloway School in Atlanta. The companion web site MCM Theater makes heavy use of Java Applets, a technology that unfortunately did not age well. The site may still give you a flavor of what I implemented back then.
This was a fun project. It combined my interest in visualization, software development, and the promotion of computing literacy. McmTheater never took off as a product, since I am terrible at self promotion.
