It also features a very cool spectrum analyzer

It runs in demo mode without a VS1053-Module connected (but then the spectrum analyzer will not show).
Source can be found at Github:

There Readme is up to date. I would appreciate if someone could test the implementation.
A few things are still missing: the tone control (equalizer) is not yet in, and the color of the spectrum analyzer bars can not be changed (only blue right now). Apart from this, it is close to final as far as functionality is concerned (code documentation is lacking, though).
I have a picture in the attachments.
