Hikari Unicornified Gravatars

Gravatar is a nice service, it allows us, as users, to define avatars related to our emails, and then those avatars are used everywhere we comment and participate, automatically.

But not everybody know or bother with Gravatars, and when we have a site we end up with a bunch of comments with the same default avatar, for every commenter that didn’t register on Gravatar, or in anonymous comments.

Hikari Unicornified Gravatars lets us “unicornify” these avatars, providing some more colors to our beloved sites :D
