[Video] Style of content (project based vs. mini examples)

Based on the content outlined in #68 I think there are two possible ways to go in terms of the video content.
Apart from for the intro to iex and types of data in Elixir, I think we could introduce the rest of the content either through little examples where we show each thing in a nutshell (here's how to use a case statement, here's how to do pattern matching), or we create a micro project and introduce concepts as we encounter them in a sort of code along style way.

I personally prefer the idea of a project based walkthrough with core libraries and stuff included, but I don't know if other people thing introducing things in a very separate way might be better?
