  // Import the net libraries

  // Declare a client
  Client client;
  // The data we will read from the server
  int data;
  
  void setup() {

    // Read data
    if (client.available() > 0) {
      data = client.read(); 
    }
    
    // The incoming data is used to color the background.
    background(data);
