A web-application, built on the Processing language (see: processing.org ) by a student from the “Arts Décoratifs” in Strazbourg, Yannick Mathey, intended to design letterforms. Explaining it would take far too long. Just take a look at the video to see how fiddling with the different parameters changes the attributes of the letters.
Yannick explains (in the comments on the Vimeo-pages) that of course he didn’t intend to replace the type designer, yet his app is designed to facilitate experimentation. For every parameter markers are set up to indicate trespassing the rules of what is commonly considered good design, yet the markers are also there to be crossed, opening up the possibilities to generate extraordinary forms.
If you speak French, you can read an extensive interview with Yannick Mathey on CG-Blog, where I found this.
(And if you didn’t know: CG-Blog also did a rather nice interview with yours truly, a while ago, which is also available in English. Go check it out! )
