“OSP (Open Source Publishing) is a graphic design collective that uses only Free, Libre and Open Source Software. Closely affiliated with the Brussels based foundation for art and media Constant, OSP aims to test the possibilities and realities of doing design, illustration, cartography and typography using a range of F/LOSS tools.
Since 2006, we investigate the potential of F/LOSS in a professional design environment. We do not expect to find (or offer!) the same experience as the ones we are used to. In fact, we are interested in experimenting with everything that shows up in the cracks.”
