Abstract-codex is a container of web based computational artworks. Main project focus is exploring and sharing the possibilities of coding as an expressive/emotional medium. In this vision the code has an ambiguous nature: it is both the material which digital works are made of and creative process. So algorithms and programming strategies are at the same time works bricks and micro formal organization. This research try to reach a personal language through an idiomatic use of the medium and a personal conceive of the content.
