Typing in Cheese

I think it was back when I was taking Geography 370 (Introduction to Cartography) that I first heard of a typeface promising to save the user 15-20% in ink and toner by creating small holes in the characters (a swiss cheese effect.) I partly forgot about it, seeing as how I don't really spend much at all on toner or ink...but the idea lodged itself somewhere in the trivia-encrusted recesses of my mind. Lately I thought about it again, and found this. Ecofont probably won't help any of you guys that much; I doubt any of my readers print in such massive quantities to make it economically meaningful.

Even if Ecofont won't help me that much, it is nice to think that there's a typeface in the world that can be described as cheese-like...not counting fontina.

Oh man...that's terrible.
