Programma is the typeface I use when programming and teaching about programming. Programma is a sans serif monospace typeface. Programma is eclectic. It borrows ideas from Microgramma, Inconsolata, Courier, Twentieth Century, and others. Programma is not suitable for most purposes, but it is pretty good at representing computer programs. Programma is still being tinkered with. Daley was inspired by ITC Machine and Susan Kare's Chicago 12. Programma and Daley are in the Public Domain. You are free to use it.
