A light eyeball widget that follows the mouse.
Windows: Download Pyes.exe and run
Linux: TBD
MacOS: Probably never
(Assuming Python is already installed) Download source, extract to a folder and run Pyes.py
If your screen scale (found under display settings) is not exactly 100% you will not be able to properly move the Pyes widget. There is no known solution as python cannot read that kind of system data.
