This is the code repository for JES, the Jython Environment for Students. It is an educational IDE used in the Media Computation curriculum developed by Mark Guzdial and Barbara Ericson at Georgia Tech. More details on the curriculum are available at http://www.mediacomputation.org/.

Inside this Software Suite, you will find all the tools you need to make pictures, audio, and video using the Jython language. Also included are, Barbara's Java mediacomp classes, previous releases of the software and JES.exe sources

JES releases are available under the Downloads tab on this site. The current release version is 4.3, which makes use of 0-based media APIs. If you need to use the older 1-based media APIs, you should use version 3.2.1.
