This is something that stands out as being a situation where people can do more than they realise, using a basic set of skills.
I started out working on tool systems as it was something that i enjoyed, and i wanted to share the fun.
It was after i realised that not everyone enjoys making things the way that i do, that i had to think about what people really needed, which is how i ended up looking the the Resilience Maps.
One resource that is worth exploring is Appropedia,
as they document a wide variety of solutions to the various niches within the overall maps.
They also have a wide range of case studies, that come from people documenting their own projects.
