 ## Background 
 
-The word animation is a medieval term stemming from the Latin animare, which means ‘instill with life’. In modern terms, it's used to describe the process of creating movement from still, sequential images. Early creators of animation used spinning discs (phenakistoscopes) and cylinders (zoetropes) with successive frames to create the illusion of a smooth movement from persistence of vision.   In modern times, we're quite used to other techniques such as flip books and cinematic techniques like stop motion. Increasingly, artists have been using computational techniques to create animation -- using code to "bring life" to objects on the screen over successive frames. This chapter is going to look at these techniques and specifically try to address a central question: how can we create compelling, organic, and even absurd movement through code?

 As a side note, I studied fine arts, painting and printmaking, and it was accidental that I started using computers. The moment I saw how you could write code to move something across the screen, even as simple as silly rectangle, I was hooked. I began during the first dot-com era working with flash / actionscript and lingo / director and have never looked back.

-The compiler found an error and did not run the program. Instead, in attempt to help you fix it, the compiler is showing you where it got confused in attempt to help you fix it. The first part, *prog.cpp*: tells you the file that contains the error. In this case, ideone.com saved your code into that default file name. Next, it says `In function ‘int main()’`: file showing you the specific section of the code that contains the error, in this case, between the {curly brace} of a function called *main*. (We will talk about functions and curly braces later). On the next line, we see `prog.cpp:5:2:`. The 5 is how many lines from the top of the file, and 2 is how many characters rightward from the beginning of the line. Next, we see `error: ‘cout’ was not declared in this scope`. That is a message describing what it believes it wrong in the code. In this case, it's fairly correct. iostream.h is gone, and therefore no `cout` is provided to us, and so when we try to send "Hello World", the compile fails. On the next couple of lines, you see the line of code containing the fallacious `cout`, plus an extra little up-caret character on the line beneath it, and that is supposed to be an arrow pointing at a character in the code. In this case, the arrow should be sitting beneath the 'c' in `cout`. The system is showing you visually which token is at fault. A second error is shown, and this time, the compiler complains that there is no endl. Of course, we know that in order to fix the error, we need to include `<iostream.h>` so let us do that now. Please un-comment line 1 and re-run the code.
