Driving a lightning bolt art installation with 8 I2C slaves

STORY

This light art installation was to cast a lightning bolt on a 3m tall by 6m wide structure populated with 1m white LED strips when the button was pressed.

After much testing, I decided to have eight Arduino Nano as passive I2C slaves just receiving commands from the I2C master and all my coding would be centralized in the I2C master. This makes controlling the code version easily and any changes does not need to re-flash all the eight I2C slaves. This was my first time writing my own communication protocols on top of I2C and I probably would exceed the maximum length of the I2C wiring distance.
