Direction Turn the Pauli exclusion principle into something you can feel — your cursor as a fermion, surrounded by words that can never occupy your space
Result A cursor-reactive particle field where 60 word-fragments flee from your position with inverse-square force, stretching and glowing as they’re repelled
The Story
In 1925, Wolfgang Pauli proposed a rule that would explain why matter has volume. Why you can sit on a chair instead of falling through it. Why the universe does not collapse into a single point.
The Pauli exclusion principle states that two identical fermions cannot occupy the same quantum state simultaneously.
In simpler terms: no two electrons can be in the same place at the same time. They are fundamentally, mathematically excluded from sharing space.
This is not a force pushing them apart. It is not electromagnetism or gravity or any of the familiar interactions. It is a deeper rule, a topological property of reality itself. Identical particles cannot overlap. Period.
This is why atoms have structure. Why electrons fill shells instead of piling into the nucleus. Why your hand stops at the table instead of passing through.
Everything solid is just exclusion all the way down.
The Take
You are a particle. Everything else is excluded from your space.
This is not metaphor. At the quantum level, you are made of fermions, electrons and quarks, that cannot share their state with any other particle. Your very existence creates a zone of exclusion around every point of you.
Nothing can ever truly touch you. When you think you touch something, what you actually feel is the electromagnetic repulsion between electron clouds combined with the Pauli exclusion of those electrons. There is always a gap. Always a void.
The closer things get, the harder they are pushed away.
This is the fundamental loneliness of matter: to exist is to exclude. To be here is to ensure nothing else can be. We drift toward connection but veer away at the last moment, repelled by the same law that gives us form.
The Tech
The Hollow uses HTML5 Canvas 2D to create a particle simulation where words drift through space, repelled by your cursor.
The physics implementation is based on inverse-square repulsion:
- 60 word particles float with gentle drift velocities
- Your cursor creates a repulsion field with a 250-pixel radius
- Inverse-square force:
force = 8000 / (distance^2), mimicking how electromagnetic repulsion scales - Closer particles experience stronger forces, creating the characteristic “push” of Pauli exclusion
- Visual stretch effect: Words near the cursor elongate away from it, as if being pulled by opposing forces
- Glow on proximity: Particles brighten as they’re repelled, representing the energy of the interaction
- Slight trail effect: The canvas clears with transparency, leaving ghostly afterimages
The words themselves are fragments of meaning: “here”, “stay”, “please”, “hold”, “touch”. Things we want to hold close but cannot. The content reinforces the concept.
A subtle void indicator, concentric rings around the cursor, visualizes the exclusion zone you create simply by being.
The Experience
Move your cursor (or finger on mobile) through the field of words.
Watch them flee. Not gradually, not gently, but with increasing desperation as you get closer. The inverse-square law means that halving the distance quadruples the force. Getting close triggers panic.
Notice how words stretch away from you, elongating as if pulled by your presence. Notice how they glow brighter when stressed by proximity. Notice how nothing ever reaches you.
The words drift toward the center when left alone, pulled by a gentle gravity toward connection. But you are always there, creating a void they cannot enter.
Try chasing a single word. You cannot catch it. You can only push it farther away.
This is what it means to be matter.
