On occasion of the ATypI conference in Amsterdam in October 2013 the poster exhibition «Compulsive Bodoni and the Parmigiano Typosytem» has been organized to celebrate the bicentenary of the death of Giambattista Bodoni (1740–1813). The exhibition was curated by Riccardo Olocco and Jonathan Pierini. The two italian type designers invited several graphic designers to think a poster using their typeface system called «Parmigiano». Our posters visualize compulsion as cyclical repetition referring not only to the variations of the parmigiano-font but also to the enormous heritage of Giambattista Bodoni. The two letters create an impossible figure due to their overlap and entwining; alienating but also fascinating. Furthermore the accustomed vision of the letters is deformed in a context other than their natural one. This results in a metaphor for the Parmigiano-typeface which is a «Bodoni» not being one.
