×5 (pronounced Times Five) is a simple typeface, constructed from a 5 by 5 grid of squares. This concept is far from new: seasoned Web designers will remember Kottke’s Silkscreen, but examples can even be found in Bauhaus-era tiles. What makes this version different/special, is that the grid is used recursively to construct more complex structures. These structures are self-similar, and behave like fractals in that sense.
×5 does not work with font sizes in the traditional sense, but rather with exponents. ×5 being the smallest, and ×52 (pronounced Times Five Squared) being the next size in line.
In theory there is no upper bound, but I have never gone beyond ×56 myself, because the exponential growth makes this impractical for multiple reasons.
×5 can be installed using Composer.
composer require acj/x5
