    FYI, the site makes no claims for the machines to work, and simply sells them as art pieces.

    Now, this is very interesting. Newton ascribed the discovery of the third law to his contemporaries in the Royal Society. He wasn't aware anyone had realized it or voiced it before them. That being the case, it is intriguing to see Leonardo had written it down as far back as the Renaissance. I am now curious to know if there's any record of it before Leonardo anywhere.

    The very first thing that came to mind upon seeing this was Zeno's paradox. I wonder what sort of person this makes me...
