I'm interested in learning how to create simple interactive and dynamic visualizations with JavaScript. For instance, I'd like to make an image of a digital clock that starts running as soon as the user hoovers their mouse over the image.
In order to learn about these things, I think it would be useful for me if there'd be a large, open-source online repository of such dynamic images, including the code. However, I haven't been able to find such a website thus far.
Therefore, I'd like to ask a question about this on one of the Stack Exchange website. I'm not sure though which one would be most appropriate for such a question -- if any.
