After creating a typical MSGEQ7+Arduino+WS2812 music visualization display and successfully taping the pieces, including breadboard, to the wall for a party, I decided I'd go all in on a more refined solution.

The original goals were to:

a) Run a FFT instead of using the MSGEQ7 so I could have finer control over frequencies.

b) Design and fab a PCB.

c) Desgin an intersting and non-tacky enclosure.

d) Tackle the ws2812 over distance problem.

e) Make it controllable over bluetooth.
