Drawing Pictures

Lesson 2 Code: https://s3.amazonaws.com/udacity-hosted-downloads/lesson2.zip

Note: The lesson2.zip file from the link above is slightly different from the one that Cay is using, although they function exactly the same. In the video, there is only a Picture class that Cay is using, but you'll find both a Picture class and a Color class in the downloaded project.

Don't forget to right-click the Picture class and Compile the program! Then you'll be able to create a Picture object and run methods on it, just as Cay does.
