Saelion

One field of light. Seven chapters. A strawberry with standards.

Each chapter is a small game, and winning one issues a receipt. Your game receipts stay in this browser. Drag the strawberry around if it gets in your way.

Evidence outranks opinion.

Receipts
These game receipts mark your progress on this browser. They are fictional tokens, not work approvals.
Separation
The games and their story worlds are separate from real projects and decisions.
Review
Look again, try another angle, and see what changes.

Game 1 · Acceptance

Four layers. Accept each one at the gate.

Press Accept while the needle sits in the green gate. Outside the gate it's rejected and that ring spins faster.

SaelionA shared setting for small worlds and stories.

SaedoA guide that helps the next step take shape.

SkeinA thread connecting ideas, play and stories.

GuardiansA reminder to look carefully before moving on.

Who does what.

Saelion Loop
The story setting that holds these chapters together.
Saedo
A guiding character in the stack. Here, its ring is one step in a timing game.
Skein
The thread that ties the rings together. Keep the needle inside the gate.
Context
These chapters are interactive illustrations. No operational tools are connected.
Game 2 · Redcore provenance

The brick remembers where north was.

Below about 580 °C, a brick's magnetite locks to Earth's field where it was fired. Steeper field, higher latitude. Let it cool, read the locked inclination, then name the kiln.

Locked inclination—
Deeper · the physics

Thermoremanent memory.

Blocking
Magnetite grains lock their moment near 580 °C as they cool; hematite near 675 °C. After that the record holds at room temperature.
Inclination
In a dipole field, tan I = 2 tan(latitude). Steeper locked field, farther from the equator.
Hearthplate
The companion idea: a fired ceramic archive plate that carries its own description.
Uruk
Sumerian scribes pressed a reed into wet clay: an upright wedge for one, a corner wedge for ten, place value in base 60. Libraries burned and the fire baked their tablets hard. Fire is how clay remembers, for a brick too.
Method
This is a simplified illustration of magnetic memory, not a laboratory measurement.
Game 3 · Address validation

Give a fictional address a clear form.

Fictional practice records. Pick the abbreviated form; this game does not validate real addresses or provide postal certification.

Record 1 of 5
Deeper · the acronyms

What certified means.

CASS
The Postal Service's certification for address-matching software: standardize, then match against the national directory.
DPV
Delivery Point Validation. Confirms the exact delivery point exists, not just that the street does.
LACSLink
Converts rural-route and renamed addresses to their current city-style form.
Pub 28
The style guide behind AVE, BLVD, STE and PKWY.
Game 4 · Pull the thread

Three crossings. No way out.

A skein is a loose coil of thread. This one is a trefoil, the simplest knot you can't untie without cutting. Spin it and pull it. Fill the meter and the invariant still holds.

Effort0%
Crossing number3, unchanged
Deeper · the topology

A knot with a hand.

Torus knot
The trefoil is the (2,3) torus knot: it wraps a doughnut twice one way and three times the other.
Chirality
Left- and right-handed trefoils are different knots. No deformation turns one into its mirror.
Unknotting
One crossing change unties it. Without cutting, zero changes ever will.
The system · every world is a planet

Pick a planet. It opens in a window.

Saelion is the sun. Each little world orbits as a planet made from its own scenery, and opens in a window the size of a phone, an e-paper slate, a 4:3 tablet or a laptop. Mars and Europa are real NASA images. The pale shell far out is an Oort cloud.

Deeper · the real neighbours

Two true worlds.

Mars
Viking 1 mosaic centred on Valles Marineris, a canyon system about 4,000 km long. Perseverance has worked Jezero Crater since February 2021.
Europa
Galileo colour view, reprocessed in 2014. An ice shell over a salty ocean. Europa Clipper launched in October 2024 and reaches Jupiter in 2030.
Gravity mode
Each planet pulls on every other with GM/r². Leapfrog integration, softened so close passes stay finite. Guided mode adds a gentle damping toward the nearest circular orbit; accidental mode leaves you with Newton.
Oort cloud
A distant shell of icy bodies thought to reach a large fraction of a light-year out. Here it is drawn far closer than scale allows.

Where the doors go.

Knight Side

Peachfall
Peach fall, then red rain, then a mint clearing and a night garden, with three doors on the last ridge.
Everfallen
A night garden falling into other ground, a knitted doll, and a Mars rover in a small window beside it.

Portraits are the Anewgam, Peachfall, Cheese Royale and Saelion artwork from your own repos. Drop any image on the strawberry or Myra to dress them in it.
