Live field theatre
Physics made visible.
PHYSIS is a browser-native instrument for four living fields: flow, growth, interference, and drift. Nothing here is a recording. The canvas reacts to your hand.
01 · flow
Momentum has a memory.
A pressure-like field bends thousands of particles into coherent streams. Drag across the surface and the system folds the disturbance back into itself.
∂u/∂t + (u · ∇)u = -∇p + ν∇²u
Advection, curl, dissipation, and pointer force are approximated in a real-time particle field.
02 · growth
Pattern is a negotiation.
Activator and inhibitor traces leave behind islands, veins, and colonies. The equation is simplified; the behavior still feels biological.
∂b/∂t = D∇²b + ab² - (k + f)b
Touch creates chemical seed points. The field then reorganizes the boundary between order and noise.
03 · interference
Waves do not collide. They add.
Taps become expanding fronts. Crossings brighten, fade, and leave a short-lived topography of where the field has been struck.
∂²u/∂t² = c²∇²u - γ∂u/∂t
The wave layer is rendered as expanding impulses over the same particle substrate.
04 · drift
The system never settles.
After your hand leaves, residual motion continues. The field becomes a slow instrument: less spectacle, more weather.
dx/dt = F(x,t) + ξ(t)
Low-frequency forcing and stochastic drift keep the composition alive without turning it into noise.
