How to install Kodi/OpenElec audio visualizations:
I had a bit trouble to find those visualizations and install them, so heres my tutorial:
Download the repository.popcornmix.zip file and save it onto a usb stick / samba server.
Repository on Github: https://github.com/popcornmix/repository.popcornmix.storage/
Deeplink to the Zip file: https://github.com/popcornmix/repository.popcornmix.storage/raw/master/repository.popcornmix.zip
Install the zip file in system->settings->add-ons->install from zip file (don’t unzip the file!)
(if you dont find install from zip go a few folders back then you should find it – .. folder at the top)
Once you have selected the file it is getting installed.
Then you go to settings->music->playback and select shadertoy.
Select get more:
If you are currently playing music in fullscreen mode you can press „m“ to display the music settings bar and on this blue icon you have to select shadertoy to activate it.
With this icon you can select between the new installed visualizations:
