I will start off by saying I am completely new to Processing so sorry if I am asking a simple question.  I recently found this code in an Arduino book and it works great for what I need.  Basically I want to search Twitter for the use of certain key words.  Once these key words are found I need Processing to draw squares equal to the number of results found for each word (i.e. if a word is found 10 times draw 10 squares).  I would really like these squares to be drawn completely randomly .  Is this at all possible? Here is the code I am using:

P.S.  Because I am new I am not allowed to add code that has a web link in it which is why there is no web address in String feed ="";

// Example 08A: Arduino networked lamp
// parts of the code are inspired
