Couple questions:
Do you want them to circle the player, or do you want them to resonate out of the player in a circular formation?
And, if circling the player, do you mean pulse in terms of alpha or zoom?

EDIT
Also if circling the player, do you want it around their waist like a hula hoop orbital path, or lengthways around the player going around their head and feet.
