LOOPY

"In a world filled with ever-more-complex technological, sociological, ecological, political & economic systems... a tool to make interactive simulations may not be that much help. But it can certainly try.

It's the ancient, time-honored way of learning: messing around and seeing what happens. Play with simulations to ask "what if" questions, and get an intuition for how the system works!

Raw code is too inaccessible. Also drag-and-drop is too mainstream. But with LOOPY, you can model systems by simply drawing circles & arrows, like a wee baby.

Want to build upon your friends' models? Or challenge your enemies' models? LOOPY lets you have a conversation with simulations! You can go from thinking in systems, to talking in systems.

Like duct tape, you can use LOOPY for all sorts of things:

However you choose to use LOOPY, hopefully it can give you not just the software tools, but also the mental tools to understand the complex systems of the world around us. It's a hot mess out there.

LOOPY is a part of Explorable Explanations, a movement to make learning active, not just passive.

LOOPY is also open source and public domain, meaning it's free for coders, educators, and just about anybody to re-use and re-mix LOOPY as they see fit. (Get the source code on Github!)
