Do other star systems spin mostly clockwise or counterclockwise?

The use of clockwise/counterclockwise is meaningless without a reference point. If you have a fan in your home, such as a ceiling fan, look up at it. It is probably spinning counterclockwise, from your perspective. But, if you were above the fan, looking down upon it, it would be spinning clockwise.

So, if we look out a star and see it spinning clockwise, does that tell us something about the star or does it tell us something about our location with respect to that star? Are we above or below it? Are we in-front of or behind it?

The direction a star spins is defined by the angular momentum of the cloud that collapsed and formed the star, which is just as easily one way or the other.
