+Down To Code? Let's get our hands dirty!  
+
+Let us see an example from openprocessing to visualize how much Processing is capable of within few lines of code.  
+Copy the code below into your Processing IDE and see the magic.

 Processing is easy to learn and is particularly useful to create multimedia contents (even in 3D) without
 having to type a lot of codes. It is so simple that you can read through the code and get a rough idea of
 the program flow.  
 However, that does not apply when you introduce external libraries, packages and even your own classes.
