How much can you take away from a picture before it becomes unrecognizable? The folks at the Dutch company SPRANQ took this challenge to font design and have come up with a way to make a font that uses 20% less ink.

Called the Ecofont, it's made by placing little holes inside the lines of the font so that when printed at 10 pt or less, it looks like a solid line.

SPRANQ isn't looking to make money off the product, so it's giving away the font for free.
