Every case study here is attached to a build you can open and use. The build is the proof. This is the write up of how it was put together, what the constraint was, and what came out of it.
Case studies go up as builds are finished, so this page stays empty rather than filling with placeholders. The builds themselves are already open.
If something here matches the problem you are trying to solve, the fastest route is to say which one and what is different about your setup.
