Spotify Pass is a speculative project that bridges the gap between digital streaming and real-life social encounters. The system visualizes music data based on the people you physically pass by during your daily commute, creating localized, ephemeral playlists. This project explores social computing and graphics visualization to show how music can serve as a connective tissue in urban environments. It turns passive data into an interactive, "whimsical" experience that encourages users to connect with their surroundings in a new way.
