Sadness is based on some experiments during Felix Braden’s stay at the Trier College of Design: "I played around with Fontographer’s blendfonts-feature (a type design tool to interpolate fonts and to minimize effort and expenditure of large families) with some files from a close designer. Since the basic elements derived from extremely varied fonts without any similarities, the concluding shapes first turned out to be rather fragmentary. From those fragments I chose the most characteristic elements and drew a whole new font."
