Texture, you say? Try this on for size: http://www.comicbookfonts.com/Code-Monkey-Constant-p/cl343.h...

It's not free, but both a) reasonably priced and b) dirt cheap during their annual sale (that Andy Ihnatko has written about at length).

It's not for everyone, but it's a "Comic Sans Mono" (if you will) that's actually not aesthetically displeasing. I use it occasionally for code, just for fun.
