title: Way to pipe or stream Array in Numpy/Scipy
body: <p>This is my specific use case to better explain the problem, but I'm looking for a generalized solution. </p>
  
  <p>I am using a Raspberry Pi with the adafruit LED display that displays an RGB matrix (this code is in Python 2). I have a python script that generates RGB data every 1/n seconds.</p>
  
  <p>Is there a package or library that allows me to continuously generate RGB data in the form of an np.ndarray in one process and have it be polled by the the matrix script so that it does near-real time interprocess communication of numpy arrays. </p>
