Changing profile pictures makes people confused.
What about an image server that updates your profile picture one pixel at a time over like 6 months so no one really notices it?

That's a cool idea.
Would gives quite funny results I'm sure and add suspens to follow even more the person to discover the next line of the picture.
Alternative is to make a gif glitching from old to new one as a temporary image.
I will not change personnaly but I don't have a pig noise outlet as pfp.
