Created by Naoki Nishimura, Helvetica Face is a Livetype format font. This new Helvetica family font changes the “typeface” based on the posting of a new “face”. The site allows you to record your face within the font, adjusting the threshold resulting in a new glyph you can download.
While normal fonts which are governed by software rules on how to show the internal form (=data), Helvetica Face doesn’t have this internal information on the form. What is does have is external data given in the shape of a image of your face, and how to show that form is the only rule. For that reason, through the given data, the form continues to change without bounds.
Livetype is a new font format which takes a variety of data and can change the form of it in real time.
