Add the circle round the pointer back

[Commissioned]

Hi,

Don't know if anyone remembers, but there used to be a little green circle that appeared around your mouse pointer when you clicked. It wasn't like Screencast-O-Matic or anything, it was a little subtle green circle which faded in and out of the screen. Pretty cool, and I and lots of other people collectively spent probably like 50 days playing with that.
Re-add it?

Thanks for reading,
