For a university project focused on "signage," our team sought to create an innovative and engaging experience by transforming wayfinding into a scavenger hunt. We designed a series of posters featuring QR codes, which participants scanned to navigate the hunt. A playful cat mascot appeared at every key point, reinforcing the campaign’s identity and making it more memorable. Each QR code led to a digital 3Dwayfinding experience, guiding users to the final destination. At the end, participants were rewarded with a unique prize: a pair of socks. This approach allowed us to blend creativity with practical design, resulting in a dynamic and memorable project.
