If you can imagine it, it can be done with computer graphics. Obviously, Hollywood has caught on to this. Each summer, we are amazed by state-of-the-art special effects. More and more of these images exist only within the memory of a computer. There seems to be no end in sight for this trend. But we're not just talking about big budget mega-productions. There are music videos, and spinning logos on the 6 o'clock news. Computer graphics is now as much a part of the entertainment industry as stunt men and makeup.
