For my first project, I want to create an audio controlled lighting system that uses delay, fft and data smoothing techniques to transform audio signal, and presents the sound pattern via multiple ways. Here are 2 ideas of how I might visualize the audio:

1. Group the 30 lights into 3 subgroups, and use time shifting to create a wave effect from the center, and use fft to control the colors.
2. Use fft to change the color but start from a random light, and propagate the new color to nearby lights.
