Rongo is an idea I was playing with for a programming language.

I had a few notes/ideas for syntax written. (link is to google docs file)

After re-reading this, I definitely am not fully keen on it, but eh, it's still interesting to document where I've been with this.

There's also a very basic starter grammar made for ANTLR written with the help of an old friend a few years ago. We didn't get further than this, and the project is currently dormant, but would be fun to revisit eventually.
