After the you guys helped me out so gracefully last time, here is another tricky array sorter for you.

I have the following array:

a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]

I use it for some visual stuff and render it like this:

1   2  3  4

5   6  7  8

9  10 11 12

13 14 15 16

Now I want to sort the array to have a "snake" later:

// rearrange the array according to this schema
1   2  3 4

12 13 14 5

11 16 15 6

10  9  8 7

// the original array should look like this
a = [1,2,3,4,12,13,14,5,11,16,15,6,10,9,8,7]

Now I'm looking for a smart formula / smart loop to do that

ticker = 0;
rows = 4; // can be n
cols = 4; // can be n
originalArray = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16];
newArray = [];

while(ticker < originalArray.length)
{
    //do the magic here
    ticker++;
}

Thanks again for the help.
