Always thought the closest we can get to time travel is music and photos, what if you combine those two media primitives into one experience where you can browse your camera roll while also listening to the music you were playing at the time those photos were taken.

Took 5'ish hours to build this with Claude & Codex. Spun up 3 different agents: (1) Spotify API integration, (2) front-end UI/UX work and (3) back-end work to parse the camera roll in an intelligent way.

Each of the 3 agents required a substantial amount of steering and back & forth to achieve the desired outcome. Fun experience figuring out how "agentic" these agents really were at the time (GPT 5.4 & Opus 4.6, actually used the non-Codex 5.4 version which worked surprisingly well).
