Loopy: a tool for thinking in systems (2017)
- dreamcompiler 7y agoI'm a big fan of system dynamics but the gray-on-gray text on the website makes it so hard to read I didn't stay long enough to investigate.
- LearnProg17 7y agoCould 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". Instead of "demotivation", you could use "motivation". So that, we wont have to worry about double negatives. I would prefer to add weights, to the connecting arrows, to give more detail.
- rounce 7y ago> I would prefer to add weights, to the connecting arrows, to give more detail. Second this. The other thing is that your diagram layout is defined by the 'weight' you want to apply to a relationship. Sometimes adding a new, less influential relationship will require moving every other node.
- subbu 7y agoLike in process flow diagrams we need different shapes to represent different ideas. Circles alone can't be used for it.
- ken 7y agoI love it! It's like the simulations of iThink [1], with the "analogic" sketching UI of GRaIL [2].

- headsoup 7y agoGreat 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.
- Iv 7y agoI'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.
- harshalizee 7y agoyou can. Just add more arrows.
- Karrot_Kream 7y agoA 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. [0]: https://insightmaker.com/ https://insightmaker.com/
- jacques_chester 7y agoSlightly annoyingly, Insight Maker supports the core idea of stocks and flows but doesn't really use the stock-and-flow notation.

- bshipp 7y agoI'm not sure how productive I'll end up being, but it's way more fun to play with than Visio.
- jshprentz 7y agoLoopy is one of several Explorable Explanations tools [1] that let people interact with models embedded in web pages. [1]: https://explorabl.es/tools/ https://explorabl.es/tools/
- babak_ap 7y agoLOOPY is made by Nicky Case! Author of interesting work such as: The Evolution of Trust (https://ncase.me/trust/ https://ncase.me/trust/), The Wisdom and/or Madness of Crowds (https://ncase.me/crowds/ https://ncase.me/crowds/)
- mlok 7y agoOMG thank you so much for this, I played the game of trust and I love it !! This is the best way today's tech can help people understand logical / mathematical facts applied to everyday life.
- paulorlando 7y agoThis is great. Thanks for building it!
- kyoob 7y agoMan, 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.
- seren 7y agoNice visualization. Does anyone know something as entertaining to represent Finite State Machine ?
