What about:

public static IEnumerable<TReturn> Infinity<TReturn>(TReturn start, 
  Func<TReturn, TReturn?> generator)
  where TReturn : struct 
{
  generator.ThrowIfNull("generator");
  TReturn? val = start;
  while (val.HasValue)
  {
    yield return val.Value;
    val = generator(val.Value);
  }
}

public static IEnumerable<double> Noise(int seed)
{
  Random r = new Random(seed);
  return Infinity(r.NextDouble(), x => r.NextDouble());
}

That's a pretty easy way of doing it, yes. Coming to think about it again after these years, maybe it's a bit odd to have an infinite enumerable? I haven't found other places in .NET where an enumerable sequence never end.

There is already a Random method, so I think this is already done.
