Input font system
Apart from writing code for fun and profit, I have a thing about fonts. It's only natural then that programming fonts have a special place in my heart. Monospaced fonts are the de facto standard, but lately a radical idea came to my attention: using proportionally spaced fonts for code and leaving the actual typesetting to the editor.
While I am still not convinced, I have to admit that the proponents of the idea, came up with a beautiful family of programming fonts called Input.
What can I say, it's my new favorite :)
