tl;dr: it's a cellular automaton on a "loom" of alternating bars, using contoured tiles to guide marbles through logic gates.
It's not just "Turing complete, job done"; I've tried to make it actually practical. Devices are compact, e.g. you can fit a binary adder into a 3cm square. It took me nearly two years and dozens of different approaches.
There's a sequence of interactive tutorials to try out, demo videos, and a janky simulator. I've also sent out a few prototype kits and have some more ready to go.
Please ask me anything, I will talk about this for hours.
