After searching the forums for a nice, clean example, I couldn't find one that is any good. Most of the ones I found use basic text functions, and the text doesn't "flow" letter by letter nicely.

I decided to make a cool RPG dialog box with writing text!! Its very similar to the golden era Final Fantasy games on NES & SNES, etc.
Here is the example you can play in your browser:
