Instruments
for Complexity

Interactive tools for practitioners working in complex environments. Each instrument is a thinking aid — not a model of the world, but a model for exploring it.

Tools & Simulations
01
Dynamics

The Pendulum Simulator

From predictable swing to deterministic chaos. A single pendulum and a double pendulum — the same physics, a completely different world.

Open tool
02
Networks

Network Science Simulator

Topology, diffusion, centrality, weak ties, and cascades. Five lenses on how structure shapes what can spread, stick, or collapse.

Open tool
05
Dynamics

Polarisation Dynamics

Opinion landscapes, echo chambers, attraction-repulsion forces, and interventions. Four tabs on how social systems pull apart — and what might hold them.

Open tool
06
Dynamics

Conflict System Dynamics

The programme reduced conflict. It also quietly built dependency, eroded local legitimacy, and left the rights dispute that drove the conflict entirely untouched. When the funding ended, the system had less capacity to hold itself together than before the intervention arrived. Seven variables, five scenarios, one structural irony — and the question most log frames never ask. Read the case brief here.

How to use these tools

Each tool is self-contained and runs in your browser — no installation, no account. They are designed for facilitation and reflection, not prediction. The point is not to find the right answer but to make assumptions visible.
