Boxer Sunrise

Boxer Sunrise is the next iteration of development on the long running and historic Boxer project. Started nearly 40 years ago by Andrea diSessa and his team at MIT and later Berkeley, Boxer is the natural evolution of educational software environments that began with Logo. Today we hope it continues to evolve and address a number of uses in education, content authoring, and general purpose computing. Most importantly, it moves forward as a reference implementation for a computational medium with the long term goal of achieving a true computational literacy in society.


The underlying Boxer code is currently undergoing a rapid transition period as the user interface and underlying source are modernized and brought up to speed after a period of dormancy. We are currently releasing alpha quality builds every 6 to 8 weeks. Stability and usability are improving quickly, but these should still be treated as development builds.

The code is all open source under a BSD license and can be found here on github.
