I would say a 14-year-old could achieve this is pretty impressive. While we give credit to his creativity and relative scientific investigation of this matter, things shouldn't be stretched too far as to recommend everybody to adopt this font everywhere. In this case, this seems the case. A printed document is meant to be read, and it is unclear if using the said font will have any impact on readability, and other usability issues. Think about it: for the sake of optimizing ink use, the trivial solution is 1) Use the smallest font sizes possible 2) Use the 'thinnest' font that arguably uses the least ink. However optimizing a single varible in this way is clearly not desirable, because it defeats the goal of printing documents. A document is meant for someone to read, no? :)
