How to make custom metabox fields duplicatable?

Question

I am now currently coding a plugin for the WordPress admin. It\'s about custom meta boxes. I would like to create a slideshow plugin, just for learning a lot of coding.

I've answered many Questions regarding this topic in WordPress StackExchange.
It is called Repeatable Fields.

But basically these are the needed resources:

• Create more Meta Boxes as needed - WPSE Q&A

• Repeatable Custom Fields in a Metabox - Gist

   * From a bespoke system, so currently not modular - will fix soon
   * Note that this particular metadata is saved as one multidimensional array (serialized)
