Uber Login Logo is a simple plugin I made so that I could customise the login screen on my own website by utilising in-built WordPress functions and the WordPress media uploader. 
Considering all the bloated plugins and resource intensive implementations floating around, I thought this lightweight codebase and clean UI could be of similar benefit to other WordPress users/developers. 
Don’t expect too many fancy bells and whistles, this plugin does one thing, and does it well.
