The final prototype delivered for this class used two of the custom LED driver boards with 30 small, white LEDs. The boards were connected to the RaspberryPi running a simple openFrameworks application. The application uses an early version of a library I'm working on for the PCA9685 PWM chip, which is the center of the LED driver boards.
The video above shows the prototype running through a generative program based on 2d Perlin Noise. I'll be using this prototype to dial in the correct noise/video ratio for the final installation in the marquee.
The openFrameworks code, as well as the in-progress PCA9685 C++/raspberryPi library can be found HERE.
Major thanks to Dale Clifford, Zack Jacobson-Weaver, Eric Brockmeyer, Ali Momeni and Tom (the person who posted the RaspberryPi i2c code I needed on stackoverflow).
