It is a collection of the typographic research by using computation. It explores the aesthetic of experimental code driven typography by using Processing created by Ben Fry and Casey Reas. Initially it began with my MFA thesis, TYPE+CODE, at Maryland Institute College of Art, in 2007, and then, it has extended to my lifetime research project since I graduated. Through TYPE+CODE II, I have experimented with traditional and cultural oriented calligraphy to reinterpret into modern and contemporary typography with the computer codes. It crosses boundaries between calligraphy, graphic art, typography, and computer art. I use letterform, words phrases, and sentences to explore innovative typographic forms and solutions by using mathematic expressions, computer algorithms such as Binary tree and L-system and libraries. They convey diversified visual messages inspired by nature, addressing environmental issues such as green design, healing through arts, exploring philosophical and religious interpretation regarding life, death and love. The updated version, TYPE+CODE III, shows the possibilities of an extension of the aesthetic of code driven typography from cyberspace to physical space by using digital fabrication and various mediums. Floral typography (TYPE + CODE IV) is a design trend that combines typography, calligraphy and lettering with floral elements. It is a computational typography system to explore legible, expressive and narrative typography with floral elements. It shows how a custom illustration can be embedded into a selected typeface to explore legible and expressive typography in a generative system. Typography is a form of art to make written language expressive by using letter forms and text. Based on the type choices, different emotions and moods can be visually expressed through the generative selfies. TYPE + CODE V (Typographic selfie + CODE) is visual research with diverse typefaces to embed visual expression into generative selfies.


To implement my visual ideas, I referenced Geomerative Library and Caligraft (,) created by Ricard Marxer, Binary Tree Algorithm(data structure in computer science composing of parent nodes,or leaves,) L-system algorithm,simulating dimensional tree forms with fractals and the fonts, Arial, Helvetica, Stanford from, in Processing, created by Casey Reas and Ben Fry.
