About this site

Nicky Case's tool for thinking in systems. Sketch a few things that affect each other, like rabbits and foxes, connect them with arrows and run the simulation to see how the whole system behaves.

When to open it

Give it a coffee break, about 5 to 15 minutes. It's best on a computer with a mouse or keyboard, and it's silent, so it's safe at work or in class. Best for big ideas and tinkering.
