Subject: Convert singel dimention array into grid

Hi,

I have been learning ruby for the past week and am completely hooked. 
Most of the code I am producing is elegant (ruby's credit), although I 
am having trouble elegantly converting a single dimension array with 16 
elements into a two-dimension grid [4x4].

Here is what I have so far:

@array = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]
@grid = Array.new

i = 0
index = 0
0.upto(3) do |i|
  j = 0
  0.upto(3) do |j|
    @grid[i] = Array.new if j == 0
    @grid[i][j] = @array[index]
    index += 1
    j += 1
  end
  i += 1
end

@grid

Thanks,
Giant Cranes
