I recently discovered that there isn't many ways to learn r'lyehian (at least not that I know of).
Therefore I desided to make a program that can help you with that.
The program can be downloaded here: https://github.com/itsAfeat/rlyehian-learner
Feel free to comment any flaws/bugs you find, or if you just have a good idea for the program.
A new function has been added... you can now learn/train r'lyehian glyphs
