Cute programs that run on your browser

People have occasionally been pointing out cute programs that run on your browser, presumably as a goad to the programmers here: hey, if someone else can do that, why can't we?

So, maybe we should have a thread devoted just to this, so such examples are easy to find.

Here's one:

    If you right-click on this or any other webpage you'll see all the linked files which the page uses. The Bezier page uses a javascript library called D3 which is what Allan and Glyn are using.

    Here's a nice page that draws graphs in real-time, as I'd suggested a while back. It really makes the graphs more exciting. Even better, this implements a classic model that's important to our overall cause:

    with an engaging explanation here:

    As you can see from the picture there, it involves some 'box model' ideas, so it also connects nicely to the 'network theory' project.

    Following Jim Stuttard's easy instructions, I made a copy of this model and put it on my website, just to see if it would work. It did!

    To save other people time, here's a tar file containing the necessary files.

    That's pretty neat. It seems the author recognizes the utility of constructing a generic system for compiling equations into model code, like I've talked about. Maybe he'll implement it in the next version!

    It could be fun to do a parametric sensitivity analysis of the World3 model (see how the output changes with respect to parameter assumptions). It would require cleaner and more modular code than this, though.

    Here's a cute one that David Tweed doesn't like:

    It shouldn't be difficult to rip the jsxgraph code and tweak it. hth.

    Agreed! I might tack onto my visualizations TODO-list.. or perhaps I should email the JSXGraph devs who wrote the example to see if they'd be interested in tweaking?
