Hello Jörg, That is indeed quite similar! I'm looking forward to reading the description.
Out of curiosity, are you doing a 16-bin FFT with one bin mapped to each tube, or something different? Also, for clarity's sake, there's no built-in backlight in my design. I just put a photography light on blue and put it off to the right when taking pictures. I thought it contrasted nicely with the orange neon glow. I don't like always having an LED backlight, because it makes the whole thing look like some kind of gaming accessory rather than an unobtrusive audio accessory. Thanks for the kind words everyone!
