Loopy is one of several Explorable Explanations tools [1] that let people interact with models embedded in web pages.<p>[1]: <a href="https://explorabl.es/tools/" rel="nofollow">https://explorabl.es/tools/</a>

A much deeper version of the tool using more systems dynamics features is Insight Maker[0]. They're a tool to actually build and simulate real life models in. The UX is a bit more confusing, but the tool is much richer.<p>[0]: <a href="https://insightmaker.com/" rel="nofollow">https://insightmaker.com/</a>

I love it! It's like the simulations of iThink [1], with the "analogic" sketching UI of GRaIL [2].<p>[1]: <a href="https://www.iseesystems.com/store/products/ithink.aspx" rel="nofollow">https://www.iseesystems.com/store/products/ithink.aspx</a>

Could we replace animated arrows between different blocks, to something that is easier to interpret. I had to train my mind to search for negative/positive sign and current state and then add it and say in my mind "encourages doing things".<p>Instead of "demotivation", you could use "motivation". So that, we wont have to worry about double negatives.<p>I would prefer to add weights, to the connecting arrows, to give more detail.
LOOPY is made by Nicky Case! Author of interesting work such as: The Evolution of Trust (<a href="https://ncase.me/trust/" rel="nofollow">https://ncase.me/trust/</a>), The Wisdom and/or Madness of Crowds (<a href="https://ncase.me/crowds/" rel="nofollow">https://ncase.me/crowds/</a>)
Great tool, though it would be good if you could set rate flow on the items or set quantities, because it gets a little crazy just working off 'events' that perpetuate.
Man, I've been looking for this forever after having seen it a couple of years ago. I just have had no idea how to Google it. Animated flowcharts? Finite automata tool? Anyway, saved to my faves now.
I'd love to be able to change the multiplier of arcs through a dynamic quantity. Here we can just state a fixed value on each arc. In dynamic systems, these multipliers change.
