Using the array, if it is "pointed" to the same point of the sky everytime, I assume these patterns change continually??

Why should they? This picture represents a time when the universe was very young and it took billions of years to get from there to here.

[petuniasevan]

Altair's right. These are massive regions of the early universe; you will not see any changes in a given area.
The finite speed of light prevents that.

By "fluctuations" I was not referring to changes in time but rather in adjacent regions of space.
