I changed mine from a henna painted bride, with a rock:
To a lotus for a matter of hours:
To an image of a part of my wedding outfit (called a dupatta), with a blue color filter - which replaces out the white light with blue, and keeps the red intact.
What does your avatar mean to you? How often do you change it?
