Ecofont is a sans-serif font that saves up to 20% of ink due to little holes in the body of the letters. It is available in the TTF format for free, but I couldn't find any license other then the guys who made it (SPRANQ) say it's "free to download, free to use". It would be really cool to have this font in Portage :]
Created attachment 310255 [details] ecofont-2.05.ebuild There is a simple ebuild to install the free ecofont. Cheers
Doesn't look like this is free anymore.
