For any lazy C# folks:

    internal class Program
    {
        public static void Main()
        {
            int numRows = 256;
            int numColumns = 128;
            for (int row = 0; row < numRows; row++)
            {
                StringBuilder rowOutput = new StringBuilder();
                for (int column = 0; column < numColumns; column++)
                {
                    if ((row & column) != 0) rowOutput.Append("1");
                    else rowOutput.Append("0");
                }
                Console.WriteLine("row/col {0}:\t{1}", row, rowOutput);
            }
            Console.Read();
        }
    }

Cool stuff, very interesting to see that triangle structure emerge.
