The Open Source Festival was a one-day music and arts festival held annually in Düsseldorf, Germany, from 2006 until its final edition in 2019. Founded by Philipp Maiburg, the event took place at the Düsseldorf racecourse (Galopprennbahn) and became known for its mix of experimental music, visual art, and design-focused programming. The festival’s name and identity drew on the open source software movement, a theme that carried through its visual presentation. [1] [2] [3]
Design and History
The festival’s visual identity was built around a distinctive, modular wordmark. A prominent feature was the stylized “S” in the festival name, rendered in a pixel-like, blocky form that echoed the digital, open source ethos of the event. This mark was used across festival posters and promotional materials, and it became recognizable enough that when the Düsseldorf youth office (Jugendamt) produced a poster with a similar design in 2014, festival director Philipp Maiburg publicly called out the resemblance on Facebook. The incident was covered by local press, which noted the copied poster featured “the striking ‘S’ that adorned the Open Source poster two years ago.” [4]
The festival’s identity also extended to its on-site programming. In 2016, the “Open Squares” creative marketplace, a pop-up gallery for young creatives from North Rhine-Westphalia, became a recurring feature of the festival. During one edition, the design collective mutabel ran a workshop where visitors could “mutabel” (customize) the Open Source Festival logo, with the finished piece raffled off to a lucky winner. This hands-on, remixable approach to the festival’s own branding reflected the open source philosophy that inspired the event’s name. [1] [5]
Meaning and Symbolism
The festival’s name and visual language drew directly from the open source software movement, which emphasizes collaboration, transparency, and the free sharing and modification of creative works. This philosophy was reflected not only in the pixel-like “S” of the logo but also in the festival’s structure: the Open Squares marketplace invited designers and artists to present their work, and collaborations with the Academy of Media Arts Cologne (KHM) brought student art installations to the festival grounds each year since 2009. The festival’s identity thus functioned as a bridge between digital culture and the visual arts, with the logo serving as a visual shorthand for that connection. [1]
