The One-Line Hunt
Find three useful lines: one painted, one grown, one made by light. Use none as a reason to cross a closed boundary.

The check-in is not proof you occupied a coordinate. It is proof you noticed something.

Choose the door yourself · choose the way of looking · earn the stamp honestly · leave no location trail
Everyone sees it differently. Everyone is still there together.
01 · Same door, six worlds
Change the view.
A single public park can be a court, composition, habitat, neighborhood room, quiet interval, and sound field. Pick a door and a lens; the prompt changes without claiming the place belongs to any one use.
○
Player view
The place is a field of fair invitations.
Find a line, boundary, rhythm, or object that can hold a cooperative game without blocking anyone.
02 · Check in by noticing
Your local stamp book.
No location permission. No account. No upload. A check-in is a visitor choosing a public door, a way of looking, and the stamp they honestly completed.
Twenty-four ways to arrive.

03 · Pocket adventures
Twelve treasures. Take none.
The treasure is a pattern, courtesy, line, sound, depth, or clean ending—not a shell, rock, plant, animal, artifact, or object removed from the commons.
Five Depths
Choose the longest safe view. Name foreground, near, middle, far, and beyond.
Three-Layer Sound Map
Find the nearest, repeating, and farthest sound. Walk one minute and try again.
The Welcome Test
Find three details that make arrival easier and one friction that could be fixed without redesigning the world.
Habitat Five
Look for evidence of water, food, shelter, movement, and season without approaching wildlife.
Ten-Touch Door
Create a cooperative rally with one soft object or only a movement phrase. Widen after ten clean touches.
Shade Clock
Find three shadows with different edges. Predict which will change fastest.
Public Table
Find a legal shared surface. Play one pocket-size game, trade one local fact, and keep space for strangers.
Color Relay
One person calls a color already present; the next finds a different source and calls another.
Slow Loop Society
Choose a clear short loop. Let the person needing the easiest pace set it.
Art Answers Back
Find a public artwork, memorial, garden, or designed form. Read its context, then answer with a pose, line, or sentence.
The Good Ending
Stop before fatigue or closing chooses for you. Hear one last sound, count people and equipment, and go.
04 · The field, not directions
A map of possibilities.
This diagram is an editorial orientation—not navigation, distance, live availability, access, or a geofence. Each door still returns to its official steward.

edge
Six arcs, no center of gravity.
Use the arcs to imagine a day, then use the official source to make a real decision.
- Choose one arc, not a mileage conquest.
- Confirm hours, closures, permits, parking, tides, weather, and current rules.
- Pick a lens that fits what is already happening.
- Finish with time, energy, people, and equipment in reserve.
05 · Original audio companions
A little sound. More place.
Four gesture-started Web Audio sketches create quiet tones in the browser. They use no microphone, recording, upload, samples, or autoplay—and they stop quickly so the real environment stays audible.
Dawn Buoys
Four soft bells for the first public door.
Court Lines
A dry four-corner pulse for cooperative movement.
Habitat Edge
Widely spaced tones that leave room for the actual place.
West Color
A descending close for golden hour and pack-out.
Keep device volume low. Stop audio where sound affects wildlife, neighbors, instruction, access, safety, or an existing public program.
06 · OPEN/25 on Spotify
Six longer listening exits.
Each mix is a separate Spotify handoff shaped for a kind of outdoor day. Spotify supplies the music and playback; PointCast does not proxy or restream it.
OPEN/25 — Dawn Loop
Marine-layer mornings and the first public door.
OPEN/25 — Court Lines
Rallies, skating, passing, and playful motion.
OPEN/25 — Garden Color
Gardens, sculpture, drawing, and close looking.
OPEN/25 — Wetland Listening
Slow habitat walks with room for actual sound.
OPEN/25 — Golden Hour Handoff
The move from afternoon games into sunset.
OPEN/25 — Fire Ring Night
Legal designated rings, current conditions, warm pack-out.
Publication truth: a playlist only becomes a live exit here after its public Spotify page and contents are independently checked.
07 · Pinterest field atlas
Fifty views. Four weather systems.
Four boards sort the same regional commons by season, area, mood, and use. The cards disagree productively: one place can invite a player and a quiet walker without becoming two places.

The privacy position
Check in without checking over.
The app does not need to know where you are. It needs you to choose what you noticed.
- No account, geolocation, map tracking, camera, microphone, analytics, cookies, or network write.
- The working stamp book lives only in page memory until “Save on this device” is pressed.
- Save uses browser local storage on that device. Export creates a user-controlled JSON receipt.
- Erase removes the PASS/25 key. Nothing is posted or matched automatically.
- A share is always an outbound, user-controlled act outside this app.
The place is shared. The view is yours.
Pick one door, one lens, one small proof. Then leave the commons easier for the next person to see.
