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 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 like this:

1  3  6 10

2  5  9 13

4  8 12 15

7 11 14 16


//So the original array should look like this:

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

Yeah, now I'm looking for a smart formula to do that

ticker = 0;
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++;
}
