Coding on a TI

I found this nifty little tool hidden deep within my math class. The TI84 has a pretty big coding community surrounding it, mostly for games, but for other esoteric stuff as well like mp3 players and even a camera or web browser. There's a site that contains a lot of this stuff, it's pretty neat. I often use my TI for Tetris and minesweeper, but there's a keyboard available that I'd like to get to improve coding speeds and take notes with. Another hopeful project is I would like to get a hold on a couple (thousand) ESP8266's to possibly make the Calc access the internet, but that's for a much later date.
