Unicorn HAT visualiser

Has anyone used a unicorn HAT to create a visualiser with the audio played on the Pi?
Some example code would be good and eventually use it within OSMC.

do you mean visualiser?
(edit: ah I see you do, theres a typo in the title ;) )

I’ve not seen one (and I’ve looked).

Keep this in mind though if you’re planning to use analog audio out (though probably not if its for OSMC, I’m guessing) : Unicorn HAT & Audio
