A collection of analyses, "tutorials", walkthroughs and literate implementations of moderately complex standalone applications.

NOTE: When I say "tutorial", it means I don't want to add tutorials like "How to make a React SPA". I want to add tutorials for things that most people have never considered making themselves, and cover aspects of the problem domain rather than the surrounding framework.
