“Form follows function” is a credo of modernist design (though the phrase itself, and its variants, have a longer history). I wanted to created designs for both the words, “form” and “function” and as it turns out the solutions that emerged were quite distinct and interesting. For “form” the solution that appealed to me was this one, a chain reflection ambigram. For “function” however (available elsewhere on this site) the solution came as a chain rotation ambigram. In both designs the form and function worked together to create interesting solutions! A good example of the core idea being explored.
