Combining animation, a feature-length documentary and interactive comic art, the Reinventing the Wheel cross-media documentary project tells the story of the biggest historical phenomenon in Slovenia – the oldest wooden wheel in the world, which was discovered in the Ljubljana marshes in 2003. The Animation Bobri voz uses legendary characters from Janez Jalen's novel Bobri to take us to the Stone Age. Then, a feature documentary film Reinventing the Wheel gives us an insight into the phenomenon of the wheel. With the comic strip Bobri voz and its smart phone app, we come full circle, back into the animation.
