Here's an interesting image:
from Webster's New World Dictionary of the American Language, second edition, ©1978: [ME. musen < O Fr. muser, to ponder, loiter, orig., ? to stand with muzzle in the air (< musel, MUZZLE)]—Sort of adds a humble perspective to this musing business, doesn't it?

Another image:
"It is interesting to note that if you turn your monitor upside down, the little caricature of you closely resembles a raccoon with a wig."

Other meanings:
Of course muse is also a noun. Sometimes it is used to name the inspirational force in a creative art. Sometimes it refers to a poet. In Greek Mythology, the Muses were goddesses of art and science, daughters of Zeus and Mnemosyne.
