Hi,
Recently I came across this video: https://www.youtube.com/watch?v=Lx8KunB0ka8
Nice idea, the black transparent acrylic front with the OLED-display!
The creator used MoodeAudio, but Volumio in combination with some plug-ins the same result must be possible.
Recently AudioPhonics introduced a new streamer:

The Raspdac-mini has the same type of front with display.
So be inspired… 
Kind regards
Harry
