### where is the SageMath "Demonstrations Project"?

I am sure most of you are aware of the Wolfram Demonstrations Project. If not, it’s a library of interactive models demonstrating different mathematical concepts. If you ~~buy ~~*buy* Mathematica you can ~~even ~~edit and experiment with the code yourself. I find it really helpful to be able to investigate something in a interactive graph to understand the relationships in say an economic model, e.g. this example of a basic supply and demand model, this more intricate Keynesian IS-LM Model, or this model that allows you to investigate income and substitution effects with different utility functions.

Friendly people here at ask.sagemath have a couple of times answered my questions by posting code to http://sagecell.sagemath.org, which I really appreciate, e.g. this visualization of logistic population growth, but **is there a way to search for SageMath code examples or some library of interactive SageMath models demonstrating different mathematical concepts like the Wolfram Demonstrations Project?** I'm also interested to share projects myself.

I think something like a SageMath "Demonstrations Project" could be a great way to demonstrate the power of SageMath in an very accessible way, and ~~possible ~~possibly contribute to spreading the awareness of SageMath.
