ES generate custom avatar like Fiverr

Hi every body,
i was looking for some services on Fiverr and i found some thing that can be intereseting for easysocial, they generate an automatied avatar for easy user based of the first letter of its first name, friendly not ?

all most of membres dont put a photo for their profil in the begening, it will be great if we can encourage them with a first custom avatar for them, i think its great as all the members will have a diffirent one and we will not have the same defaut avatar for all people !
