Over the past few years, i've developed a strong interest in dutch style design and in particularly, dutch typography. This has come about due to numerous visits to the Stedelijk Museum in Amsterdam, combined with some targeted research towards dutch style type.
I came across Jurriaan Schrofer, a dutch typographer, mainly overshadowed by the reknowned Wim Crouwel. Schrofer's work combines legibility and illegibility and pushes the boundaries of a cohesion of the two.
I'm not quite sure if it's just the picture, but Schrofer seems a bit typography's equivalent of Albert Camus of the literacy world. Schrofer is regarded as a 'computer-design before the computer'. Frederick Hyugen describes his work as research into perception, visual effects and the optical illusion of perspective: or the interplay of letterform, pattern and meaning.
Unit Editions has published a fairly decent book of his work, containing essays and a little bit of context.
