Divide array into an array of subsequence array

This is quite cute:

static class ChunkExtension
{
    public static IEnumerable<T[]> Chunkify<T>(
        this IEnumerable<T> source, int size)
    {
        if (source == null) throw new ArgumentNullException("source");
        if (size < 1) throw new ArgumentOutOfRangeException("size");
        using (var iter = source.GetEnumerator())
        {
            while (iter.MoveNext())
            {
                var chunk = new T[size];
                chunk[0] = iter.Current;
                for (int i = 1; i < size && iter.MoveNext(); i++)
                {
                    chunk[i] = iter.Current;
                }
                yield return chunk;
            }
        }
    }
}
static class Program
{
    static void Main(string[] args)
    {
        List<byte> bytes = new List<byte>() {
              1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 };
        var chunks = bytes.Chunkify(4);
        foreach (byte[] chunk in chunks)
        {
            foreach (byte b in chunk) Console.Write(b.ToString("x2") + " ");
            Console.WriteLine();
        }
    }
}
