I was just wondering how long it would take someone to build an adder. I wouldn't be surprised if someone went for it.
Adders are curiously simple! You just need a clock, otherwise they kind of break. How you clock weights ... hnng, no ideas there.
Fun fact, if you can build a NAND gate or a NOR gate, you can derive all other functions. This is called functional completeness.
And you have to be able to compose gates. Not to detract from a very cool demonstration, but it appears that all of the energy comes from the "inputs" which have to overcome all of the frictional forces in the system. With semiconductor gates, each gate provide the energy required to drive the gates it is connected to which facilitates composition.

Yes, this system is also prone to 'fuzzy' states due do slight variances that would multiply quite a bit if used for a full computation. It'd be cool to see a rectifier for this system, which will guarantee a full 1 or 0 state given a marginal state, though I'm not entirely certain how you'd build one.
That's a cool implementation. It reminds me of domino logic gates: https://www.youtube.com/watch?v=SudixyugiX4 .

edit: btw I can recommend every engineer watches this BBC series "what do artists do all day". The thinking processes of artists share a lot more with engineering that I expected and I found all episodes absolutely fascinating.
Extremely impressive. Almost tempting enough to try and build an adder, but I fear for anything larger than a few gates the concept starts to become clunky to implement (see the gates at the end of the video ..)

This is incredible! After hearing about the MIT tinker toy optimal tic-tac-toe machine[1], I built a half-adder out of dominoes[2] around the same time period as that video and hadn't ever heard of anyone else messing with the concept.

The rest of the blog is pretty interesting too.
