The first app for astrology where you don't get any answers. An environment that encourages you to go explore and learn all the unknowns about yourself.
Stellium is the first artifact in the Astro / Esoteric family by Simulacra. A spatial knowledge environment built on the principle of "as above, so below" — re-read for the Pluto-in-Aquarius age, where the lines blur between things and beings inhabiting the revolutionary frontier.
You are not a speck of dust in the infinite vastness of the cosmos. The entire universe — with all its planets and stars — conspired together to birth you. This miracle we call life.
| Role | |
|---|---|
| Creative Conceptualization | Vedant Shok Natarajan |
| Implementation · Creative & Technical Cognizing | Vismay Hegde |
| Studio | Simulacra — instagram.com/end.of.knowledge |
| Core Principle | No interpretations are provided. The app is a spatial environment where knowledge must be actively discovered. |
| Thesis | The user is not a speck of dust — they are the universe, experienced subjectively. |
| Genre | Astro / Esoteric. 21st-century application of as above, so below. |
| User Flow | Exploration → Discovery (unlocking) → Synthesis (report) |
| Wordmark | Seanor — logo only. Acts as primary entry point. |
| UI Text | Helvetica Neue · set in Small Caps throughout |
| Labels | Space Grotesk |
| Aesthetic | Dark mode. HUD. Symbolic precision over decorative fluff. |
| Reference | Time Nomad |
Not a contained object. It fills the entire field of view. Edges are never visible.
Exterior View — camera orbits outside the orb. Planets appear as very small, distant dots. The glass creates a refractive impression — not literal physics, but the feeling of looking through glass at something vast inside.
Interior View — first-person from the Singularity at the center. Planets rendered photorealistic. Glyphs project onto the interior surface. The sphere is the sky around you.

One system visible at a time. Toggling shifts the entire environment.

Every field in the birth entry form carries a Latin sublabel:
| Field | Latin | Translation |
|---|---|---|
| Name | nomen | "that by which one is called" |
| Date | dies natalis | "the day of one's birth" |
| Time | hora nativitatis | "the hour of nativity" |
| Place | locus originis | "place of origin" |
Header: porta nativitatis — "gate of birth"
- Click a locked glyph → name reveals
- Click the name → expands to Degrees · Sign · House
- The HUD sidebar populates as you discover
- Aspect lines draw between unlocked endpoints
- Unlocking Rahu / Ketu gates entry to the Vedic layer
- Completing Vedic gates entry to Chinese / Four Pillars
A sequential decomposition — eleven layers, one aspect type at a time. Conjunction · Opposition · Square · Trine · Sextile · Semi-square · Sesquiquadrate · Quintile · Biquintile · Semi-sextile · Inconjunction.
Each reveals its own small truth. The final synthesis is named by the dominant quality of the moment — "Hopeful and Tired," "Urgent and Still."

Birth data is a combination lock to your life. It is not stored. It is not shared. It exists only to map your sky — in your browser, for your session, and then it is gone.
