I came across some very cool fonts which are ideal for my terminal windows in Linux. I'd been using plain old fixed for now, but that's a little large for a 1024x768 laptop screen, and anything smaller I've found has been unreadable.
I hunted around a bit and came across Proggy Fonts, designed for coding and available in small yet legible styles. I'm now setup with Proggy Tiny for my main terminal font, with Proggy Square for when need a slightly larger font. Small yet clear and now my screen's got much more usable real estate!
