OsloNight, a one-day culture festival in Basel, asked us to develop a new poster system for the yearly festival. We created a strong graphical layout evolving around a shape combining the letters O and N. The shape can be seen as a keyhole into the festival. The shape contains the key visual of the year, which this year was freshness and fruits. We designed posters in A3 to F4 format, flyers, stickers and a wayfinding system so the visitors could find the specific events during the festival. The design was made in collaboration with Hyun jun Jang for House of Electronic Arts, Basel.
