Sorry to sound pedantic, but there is an important difference in emphasis
between something being 'harmonic' and something being 'harmonious'. I think
this might be what caused people to respond to your original question in
terms of sine wave interaction! Maybe what you are looking for is something
which sounds 'harmonious'. This may, or may not have anything to do with
harmony in the musical or acoustic sense.  N.B: Sounds which we can
objectively call 'harmonic' (according to a definition) are not necessarily
*perceived* as 'pleasant' - it is often the structural function of the sound
which determines its psychoacoustic effect.

If you want to create 'ambient' music which sounds harmonious (to you) I
recommend that:
1) You sell your computer and by a Korg wavestation ;-) (..only joking..)
2) You take an aural approach to composition, and use trial and error until
you find something which pleases you (... in the process you might stumble
across something which takes you in a new direction..)
..From what I have seen, this is the way many 'ambient' artists tend to work
(aided by a few hallucinogens of course!).

Good luck in finding the ultimate fluffy clouds...
