The Liminal Web

Between presence and distance, between meeting and world, between knowing and searching — this is the liminal web.

Castalia

A 2D world for the liminal web

Walk through pixel maps, drift into conversation zones, and build shared spaces — a new kind of online presence.

  1. 01
    Enter a living 2D world
    Walk through pixel-art maps as your avatar. See others moving in real time. Castalia is a place, not just a call.
  2. 02
    Drift into a talk zone
    Walk close to someone and audio opens automatically. Step away and it closes. Proximity audio — the way conversation actually works.
  3. 03
    Connect with video orbs
    When you're in a zone, floating video orbs appear above avatars. See faces, read the room, without a full-screen grid.
  4. 04
    Build your own space
    The built-in map editor lets you design custom worlds — draw rooms, place portals, set talk zones. Your community, your map.
