Avatars are a part of any community website/app and, if you ever found yourself hunting for them, here is a handy solution.
uiFaces is a website that presents a list of avatars and allows us to customize them.
The customization options are the size of the image, spacing and the radius of it.
Once the output looks good, we can just take a screenshot and use it in mockups. Something simple yet useful.
