Running mopidy with music visualizer

I finally equipped my media room with surround sound and was looking for a media solution to play my ripped CDs. The latest solution I’m using is mopidy connected to the tv thru HDMI. However I wanted a little something on the screen. I missed the music visualizers that were popular on Windows 15 years ago. My final solution was using gstreamer output in mopidy.conf.

Im using the following command in my mopidy.conf file.
output = audioconvert ! audioresample ! tee name=t ! queue ! autoaudiosink t. ! queue ! audioconvert ! spacescope style=color-dots ! video/x-raw,width=2560,height=1024,pattern-aspect-ratio=1/1 ! videoconvert ! fbdevsink

Its not using X-Windows but instead displaying on the frame buffer (console screen). Without X-Windows the performance is a bit better.

Currently its running on a RPI 400 but Im thinking about getting a cheap dell optiplex off ebay. It will fit in along with the other equipment and its cheaper than a RPI 5
