3d Cursor, only Ob Centers

They prevent rotation/scaling from effecting the scale/rotation of the objects and just effects their position.
This is handy for aligning objects if you constrain to an axis and scale, as well as other neato things :)

Intrr came up with the code and I hacked it into the GUI
