What NetLogo Web actually is

The browser version of NetLogo opens its full model library: wolf and sheep predation, ant foraging, segregation, virus spread, flocking, traffic grids and forest fires. Each model exposes its parameters as sliders, and the code behind it is readable on the same page.

Why it is worth your time

Opening the code tab and changing the rule that produced the behaviour you just watched is what separates this from a gallery of finished demos.
