This program goes out and scrapes (reads) the front page of the new york times. It looks for the words "peace" and "nuclear" and tallies the number of times they appear. If peace occurs more than nuclear the background is set black which blacks out the nuclear lettering leaving the peace lettering intact. the opposite happens if there are more instances of nuclear. If they are equal the background is grey and both are visible. So even when you think you are reading just one the other is always there, the context is the only thing that changes. Think about it.
