OK. Here is the list of some the software I write; see if you may be interested in any of these programs, possibly. (All of them free open source; a Fossil repository is also available for each one, in case you want to look)
- Bystand: A simple NNTP client with a command-line interface and using SQLite to store the articles.
- Farbfeld Utilities: A set of filter programs to make and alter pictures (including some effects that I have not seen in other programs, such as the ability to make the tensor product of two pictures), and to encode and decode various formats.
- Free Hero Mesh: A puzzle game engine, for turn-based grid-based games, like Everett Kaser's Hero Hearts.
- TeXnicard: A program to make a database of and to render cards for card games such as Magic: the Gathering and others. It is programmed with a combination of PostScript and SQL, and is itself written in C and also supports TeX fonts and TeX typesetting. If you have used Magic Set Editor, this is a similar idea although there are many things I don't like about MSE, so I made a better one (well, better in my opinion).
Maybe you are not interested in any of these programs, which is OK, but if you are interested in one then you can try to make a logo, make further inquiries, look in the Fossil repositories, or whatever else you might want. However, please note that I am unable to pay (as I have no way to do this; sorry).
These programs are not necessarily complete, although the first two are complete enough to use for their purposes (even if some features are missing); the other two are in progress, but some work has already been done.
I also don't know if a logo is needed or wanted, or what the logo would possibly resemble, because I am not a artist, but maybe you or someone else knows, even though I don't know.
