    That represents and emulates a famous historical attempt at calculation. Even Sexier!

    ooh. That makes an abacus obsolete :rofl:. Id rather use that than a four-function calculator, or perhaps even a slide rule, the temptation is too great.

    And im sure that will certainly beat a graphing calculator anyday.

    That is a really beautiful bit of construction. If you're interested in that sort of thing in general, I found an outstanding example in a Scientific American article last year. I can't remember what issue, but I found a web site for them (they still make the things, and have since 1947). It's called a CURTA calculator. The thing's about the size of a pop can and has hundreds of parts. It also uses some weird thing about adding reciprocals or something like that in order to subtract. (I really only have about a grade 9 math level, so I don't understand it too well.)
    I don't know how to make links or put up pictures, but I copied down the address: www.vcalc.net/cu.htm :approve:

    Really...? Cool... I tried using my Liebnitz, but the ADSL line was incompatible with the grommet on the back.
