01 · CAST & WAIT
Cast, then wait.
Once the bobber touches the water, an 8–18 second wait begins. Just before a bite, a shadow drifts toward it underwater.

MAC DESKTOP PET · FISHING
A macOS pet that fishes leisurely in the corner of your desktop. When Claude Code or Codex finishes a task, it reels in a message bottle.
Browser demo. The real app floats transparently on your desktop.

Petting draws a heart, dragging stretches it, a quiet minute means a nap. A "change the bait" reminder nudges you to rest too.
