I've been involved in tuning theory research for quite some time, and have put together some miscellaneous music theory utilities for people to use. Here are some of them:

• An interactive MOS tree ("Ls" format), based on UnTwelve's Stern-Brocot tree app.
• An interactive MOS tree ("ab" format), based on UnTwelve's Stern-Brocot tree app.
• The original UnTwelve Stern-Brocot tree app the above are built on.
• A "flat horogram" MOS generator.
• A Harmonic Entropy calculator.
