Cozette is a bitmap programming font optimized for coziness. Cozette is based on Dina, which itself is based on Proggy. It's also heavily inspired by Creep.
Cozette is distributed in two main variants: bitmap and vector.
Bitmap fonts are, effectively, just that - bitmaps. They scale terribly, but look nice and sharp (and pixel-perfect) if you use them at their intended point size. Vector fonts scale well, but in this case, might look ugly at smaller point sizes because of antialiasing issues and the like.
