Editing Category:Demonstrations

Let's collect self-contained examples and demos here. I'm imagining this to be a space for demos that don't link to the main software stack, and focus on implementing a single feature or concept at a time.

Preferably, they should use no external dependencies, or have only a single external dependency. They should be easy to install and run without extra knowledge - the main usage method should be readily apparent and the code should follow documentation conventions.

Most importantly, these should be short and easy to read, because their purpose is to teach the group. It would be great if we could demonstrate, discuss and come to understand these projects within one or two group meetings.

These demonstrate or introduce new concepts, conventions, libraries, patterns, etc.
