×5 (pronounced Times Five) is a simple typeface, constructed from a 5 by 5 grid of squares.
This concept is far from new: 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.

Also, other rules and variations can be introduced to create non-standard glyphs.
These fall into two categories: static (red) and dynamic (blue).
The static ones represent characters like ligatures and monograms that do not have a code point in the Unicode standard.
The dynamic ones include extra algorithms in order to introduce principles of Nivan figures and randomness, et al.
