Interactive Systems Simulator

Small assumptions.
Radically different outcomes.

Explore how invisible forces — contagion, compounding, inequality, and network effects — actually behave. Adjust the assumptions. Watch the consequences.

Spread & Contagion

How things move through populations — disease, ideas, influence, truth, and lies.

Compounding & Growth

Small edges repeated over time. The most underestimated force in the universe.

Power & Influence

How wealth, networks, and scale create nonlinear advantages.

Probability & Luck

Why randomness fools us and how tiny edges get mistaken for genius.

Society & Trust

The invisible structures that hold communities together — or tear them apart.

Systems & Resilience

Why optimized systems break and redundant ones survive.

Human Tradeoffs

A life is a limited budget. Every peak creates valleys. Every strength casts a shadow.

Most people think linearly in a nonlinear world. These simulations exist to correct that.
