SUPERPOSITION HELD · NOT YET MEASURED
Pre-decoherence Interface

It is here
and there and there
until you look.

Kexwisp renders the frame before observation. Elements drift as probability, not objects. Hover to collapse the wave. Click to force a measurement — and watch it split.

Things that haven't decided

ψ-01

Superpose

Exists in five positions at once. Only the average of them is useful. The truth is the distribution.

P(position) = 0.62 | 0.21 | 0.17
ψ-02

Interfere

Two copies of the same data meet. They don't add — they cancel, reinforce, leave stripes.

visibility = 0.88
ψ-03

Decohere

The environment keeps measuring us. So we freeze into one shape. Sad, but legible.

τ_decoh = 1.4e-7s
ψ-04

Entangle

Two cards, no matter where, share one state. Flip one — the other already knows. Don't ask how.

fidelity = 0.997
ψ-05

Tunnel

Information in a box with walls too thick. It leaves anyway. Probability has no respect for barriers.

P(escape) = 3.1e-4
ψ-06

Collapsed

The only honest one. Already looked at. Now just a grey rectangle pretending to be stable.

P = 1.00 (regret)

The double-slit UI

With Observation Off

Each packet passes through both slits. The screen behind fills with interference fringes — bright, dark, bright. No single path exists.

Turn the observer on, and the fringes vanish. You get two dull bands, like a classical bullet. To see the magic, you must agree not to look.
