The biggest project I've worked on: ASCIIpOrtal
I don't drop in as much as I once did... which wasn't much. But I wanted to plug my current project which I just got to what I'm calling my final public beta. It's called ASCIIpOrtal. It's Portal, in ASCII. I'm using the PDCurses library and hope to integrate sound with SDL, tho I've never done that so hopefully it'll work. If anyone has any experience with this, let me know.
Meanwhile, you can get more information here as well as downloading the source and windows binaries:
