The only software project I donate to is NVDA[1]. It's an open source screen reader, AKA software that makes it possible for the blind to use computers through synthesized speech.
It's one of the few open source projects (besides Blender and GIMP) that is used directly by non-technical end-users and that has managed to surpass its commercial brethren , both in features and popularity. This is partly due to its extreme, almost Emacs-like hackability and a vibrant plugin ecosystem, which provides everything from better speech synthesizers to accessibility enhancements for other apps.
It has been created by two guys in Australia, mostly in response to the outrageous prices of commercial screen readers (~$1500 for noncommercial use). The situation has gotten better since then, Windows now comes with Narrator, which is... usable, but NVDA is still the top contender for most (non-enterprise) use cases.
