FFT-enhanced colourful effect.
This features a rotating dot cube with jazzy background (though it'll just be blank without music).
- The palette is split between the cube - brighter the closer it is - and the background.
- The background has a 'copper' style recolouring each scanline.
- There's a post-processing effect that dissolves some of the cube's pixels if they are further away.
Code hasn't been cleaned up for presentation, and probably won't be.
Ensure you run on the TIC-80 with FFT hack, otherwise the fft() calls will not be recognised.
