Sprout is a font created within a 3 x 5 grid using only squares and quarter-circles. The font is all lowercase and the ascenders and descenders are the only objects that extend to the first and fifth rows respectively. I am currently in the process of adapting this modular design to an entire variable font.
These above animations stemmed from the process of designing each letterform. When moving each set of shapes around from letterform to letterform I wanted to see how the letters might look animated. The first animation shows how the letters grow from a single building block while the second shows how the constraint of the 3 x 5 grid can allow the letters to morph into each other. The following images are from a booklet I made to explain my process.
