[Harry Potter] If Harry uses the invisibility cloak backwards.. What does he see?

Let's assume the invisibility cloak works only on one side. If Harry puts the inner side out, what does he see?

To give a slightly different answer, it's possible the magic of the cloak can detect the shortest distance between its two surfaces, and uses that to work out which the "inner surface" is. So regardless of which way round Harry wears it, it will always be the smaller volume (ie him, as opposed to the rest of the world) that will be invisible.

Another implication of this theory is, if the cloak is laid out flat, both surfaces are infinitely far apart from each other, so nothing is made invisible.
