I have a Cemetech Account, where I post some of my projects, and I even have a Codewalrus Account, even though you might not be able to see it without an acount of your own.
You can check out my GitHub account here, and my StackOverflow account can be viewed here.
I own a TI-84+CE and I program it in TI-BASIC from time to time. All of the project links lead to pages where you can download them!
As always, check the README.txt files in the downloads for more info. This is a list of my favorites, but there are more in my Cemetech profile, linked above.
