Nowadays plenty of fonts are available worldwide in digital format. Painted urban signs, however, precede the era of digitalisation: in most cases they were hand-crafted by unknown artisans and often resulted into unique letterforms. What if these beautiful "unintentional" pieces of type design became actual fonts available for everybody? I had fun sketching a concept for a mobile application - Typolis. By scanning physical signs, the app would generate an entire digital typeface based on the existing hand-painted glyphs. The generated font would then be available to download and use.
