Effimera
A living map, not an ordinary one

Leave a mark where you are. It lives two hours, then it fades.

Effimera is a geolocated, ephemeral social layer. You leave a Geoemoji where you are: it lives about two hours, then it fades. But whoever passes nearby can find it, gather around it, donate it time — and keep it alive together with you. No profiles, no feed: only moments over the real city, and the people who choose not to let them go out.

It's born. It lives two hours, then it will fade.

A map that breathes

The city you know is made of people, not addresses. Effimera draws it as a living page: every mark someone leaves is a real moment, struck where they stand and with only a couple of hours ahead of it.

On the map, marks appear where people are right now. Others nearby find them, gather around them, donate them time to keep them lit — and when no one saves them, they fade, making room for the next. No profiles to curate, no endless walls: only the city breathing in real time.

Not permanent profiles
but moments
Not an endless feed
but small rituals
Not forever
but now, together

The Geoemoji, struck into a Gettone

The base unit of Effimera is the Geoemoji: a mark you leave on the map. It takes shape as a Gettone — a coin of pressed metal, struck with an emoji. You set it down where you are, and from that moment it begins to live: it starts with two hours ahead of it and stays there, open to whoever finds it.

Tied to a place
It lives where you left it; it doesn't follow you.
A short life
A couple of hours, then it fades.
Mostly anonymous
The gesture matters, not the name.

The life of a mark

Every Gettone follows the same arc. That is what makes the map alive.

  1. 01

    Birth

    You set down your Gettone. It's born with two hours ahead of it.

  2. 02

    Breath

    It lives quietly: the ring of time drains, gently.

  3. 03

    The crowd

    Others find it, gather around, and give it warmth.

  4. 04

    The rescue

    When it's about to go out, someone donates it time.

  5. 05

    The fade

    Sooner or later it fades. It leaves its moment behind.

Small collective rituals

Leave a mark

Choose an emoji, set it down where you are. A moment becomes a place.

Keep it alive

Donate time to a Gettone and stretch out its hour.

Gather

Find the marks nearby and gather them into something larger.

Rescue the fading

A mark is about to vanish — revive it before its last breath.

How it works

  1. 01

    Open the map

    Open Effimera and see the living city around you: the Gettoni people have just left, each with its own time running down.

  2. 02

    Drop your Gettone

    Choose an emoji and tap it down where you are: your Gettone is born, with two hours of life ahead. Your moment is on the map, for whoever comes by.

  3. 03

    Keep it alive, together

    Before it fades, you and those nearby can keep it alive: donate time, gather, rescue it at the last breath. This is what the map lives on.

Manifesto

We believe moments matter precisely because they end. Here is what holds Effimera up.

  1. Nothing lasts forever. It is not a flaw to fix: it is the reason a moment carries weight.

  2. We don't ask who you are. We only ask where you are, right now.

  3. The gesture counts, not the name. An emoji left on a street corner says more than a thousand profiles.

  4. The city is not a map of addresses: it is a living layer of people, moods, presences. Effimera makes it visible.

  5. A mark alone goes out. Together we keep it lit. Care is a shared gesture, not one person's duty.

  6. No feed to fill, no archive to guard. Only small rituals that happen and pass.

  7. We tend to fragile things precisely because they are fragile — and we let them go when it is their time.

  8. Being here leaves no permanent trace. It leaves something rarer: the proof that we were here, together.

Nothing lasts forever. That's exactly why it's worth being here now.
