The Odds of Your Existence

witness 300 million unique sperms in 365 days

The Odds of Your Existence

Every human life is the result of an extraordinary cosmic lottery. In the race to fertilization, approximately 300 million sperm cells compete, but only one succeeds.

The stream you just witnessed represents this abstract number in real-time. Over the course of one year, we visualize all 300 million participants — each one a potential life, each one unique, each one representing the same astronomical odds you overcame to exist.

Your existence is a miracle.

This project is a meditation on probability, existence, and the sheer improbability of consciousness itself. You are here against odds so vast they defy comprehension. That makes your life — every moment of it — infinitely precious.

Deterministic Synchronization

Unlike traditional visualizations, this simulation is not random — it's perfectly deterministic. Using a shared seed and synchronized time, everyone viewing the simulation sees exactly the same sperms at exactly the same moment, anywhere in the world.

The visualization runs at a precise rate: ~9.5 sperms per second, spawning all 300 million over exactly one year. No servers, no synchronization protocol — just pure mathematics and the shared experience of time itself.

Provable Rarities

Not all sperms are equal. Using the drand randomness beacon — a distributed network providing verifiable, unpredictable randomness — we assign provably fair rarity tiers to sperms.

These rarities are time-released in 10-minute window intervals: they cannot be known in advance, cannot be manipulated, and are cryptographically verifiable by anyone. The rarest sperms are true cosmic anomalies — 1-in-a-million events in an already improbable universe.

Your Unique Timeline

Life is a delicate balance between determinism and randomness. The stream above is synchronized for everyone — as long as it remains untouched, we all witness the same sperms at the same location, anywhere in the world.

But the moment you interact — pushing sperms away, drawing barriers to alter their paths — you create something entirely new: your own timeline. A unique branch of reality that exists only for you.

This mirrors the nature of existence itself. We're all part of the same cosmic flow, yet every choice, every action, every moment of free will creates a ripple — a divergence that makes your path through life irreplaceable and uniquely yours.

Try It Yourself

Use the Show UI toggle button in the hero section above to enable the simulation UI, then:

  • →Click or tap to push sperms around
  • →Enable barriers to create obstacles in the stream
  • →Start drawing by toggling Drawing: ON or press B
  • →Watch as randomness and your choices intertwine

The Future: $ZWIM & Prediction Markets

Our provably fair rarity system opens up exciting possibilities for Web3 integration. Imagine prediction markets where you can bet on when the Golden sperm will appear, or which 10-minute window will contain the most rare events.

The $ZWIM token will power this ecosystem — a memecoin with real utility, backed by verifiable randomness and the profound philosophy of improbable existence.

Coming Soon

  • →Prediction markets for rare sperm events
  • →$ZWIM token utility and governance
  • →NFT collections for witnessed rare moments
  • →Community-driven expansion of the Zwimmers universe
