Zażółć gęślą jaźń is a typographic experiment with the shortest grammatically correct sentence containing all Polish diacritical characters. The authors Marian Misiak and Oskar Zięta created this installation on a pedestrian bridge that connects the YMCA and the Provincial Secondary School Complex in Gdynia, Poland. The public space intervention was organized by local studio Traffic Design.
The shapes of letters in Maria Connected and Unconnected are determined by FIDU technology – an experimental method of creating metal objects formed with air, patented by designer Oskar Zięta. It is both a typeface and the metal letters can be used in wayfinding systems. Several dozens arrows and pictograms have been designed with this application in mind.
