I have been trying to decipher the hidden message since Monday through the computer screen. Today, my father printed out a copy of this picture. After careful observation, we find out that the method to understand the message is by looking at the printout at certain angles and look carefully to get the message. The messages are:

Message 1 - At first you only see
Message 2 - Weird shapes and lines
Message 3 - Then somebody helps
Message 4 - And a miracle happens
