I want to mention the concept of walkabout and then go for a meander with the ohmaps idea. The idea is to eventually look at if the ohmap extends from resistance (DC behaviour circuits) to impedence (AC circuits) in any useful way.

Let’s go walkabout

For quite a lot of years I would go walkabout and not really thinking about what that meant.

Walkabout is my expression for when I’m thinking about one thing and then I go off in some other interesting direction or I try to generalise something. The original ohmap idea is a good example: I was just sketching some trivial code for building image montages, and I later spotted the simple mapping to resistor networks.
