    The only odd thing I found is that the article mentions "8 neighbors" but that screwifies things when an electron approaches a corner (you end up with 2 heads in a row). It seems to work much better when you only count the neighbors at the sides (and not the corners).

    ok, just to make that sure:
    Code:
    TE
     WWW
    TE
    turns into:
    WT
     EWW
    WT
    
    (so the two electrons eventually overlap)
    
    and the case
    TE
     EWW
    WT
    
    turns into
    WT
     EEW
    WW
    
    so one tail is overlapped by a head?
    so my question is if those overlaps are allowed - maybe im thinking too much about nibbles where that would be a crash

    Your second one is wrong. You should've had
    Code:
    TE       WT
     EWW  =>  TEW
    WT       WW
    System: Debian Sid and FreeBSD 7.0. Both with GCC 4.3.

    Can we get some clarification on whether to use 4 neighbors or 8 neighbors for the simulation when determining which pieces of wire turn into electron heads?

    8 neighbors works fine for 45 degree turns in the wire, but when there's a 90 degree turn like in the example file you end up with 2 electron heads in a row.

    The animations on the Wolfram site show multiple electron heads at various points.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    it's a clock, not a gun.
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }

    Okay, this is fun so I've been going kind of nuts with this stuff. A really ugly adder:
    Code:
    delay=0
    ....................................
    ..WWWWWW............................
    .W......W...........................
    ..WWWW...W..........................
    ......W...W.........................
    ..TEWW.....WWWWWWWWWW...............
    ....W................W..............
    ...W....WWWWWW......WWW.WWWWWWWWWWW.
    ..W....W......W.....W..W............
    .W......WWWW...W.....WWW............
    .W..........W...W.....W.............
    .W.TEWWWWWWW.....WWWWW..............
    .W........W...............WWWWWWWWW.
    .W.....WWW..WWW..........W..........
    ..W...W....W...WWWW.....W...........
    ...W...WWWW..W.W...W...W............
    ....W.......WWW..W.W..W.............
    .....WWWWWWW.W.WWWW..W..............
    .................W.WW...............
    ....................................
    Red = Input bits
    Blue = Result
    Green = Carry

    Definitely open to suggestions and critisicm.

    nice! keep this up and we'll have a whole catalogue of circuits by contest end. =) care to make a full adder now?
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }

    Okay, I guess I'll have to learn how to use ncurses if I want to participate. It's about time I did anyway.

    So you all need a premade map? I know of one, but instead of being 80 by 24 its 631 by 958.

    Enjoy.

    Here's a shortened version of a binary counter, if that's of any interest.
    Code:
    delay = 10
