A Winter Wonderland In this lab, we'll use OOP for graphics programming and add some interactivity to the application.
Your Classes
The Drawable Class
In this week's lecture we discussed how we can used object oriented programming concepts to make graphics applications more organized and easier to create. One of the things that we'll leverage is inheritance, polymorphism, and abstract base classes.
We have included drawable. py that contains an abstract base class called (shocker) Drawable
Interactivity
Finally, we'll allow the spacebar to toggle the animation. That is, the first time it is hit, all the snowflakes stop falling. The next time, they resume falling. Etc…
Extra Credit
For extra credit, when a Snowflake is spawned also assign it a maximum y value that is somewhere (randomly) between the start of the ground plane and the bottom of it. Then when a Snowflake hits its maximum y value, it no longer animates. This should make it look like the snow is sticking to the ground!
Scoring
The score for the assignment is determined as follows:
25 pts - Implemented and Demonstrated the Rectangle derived class
25 pts - Implemented and Demonstrated the Snowflake derived class<
35 pts - Create the basic animation correctly
15 pts - Spacebar correctly toggles animation

answer; the above statement is (false); a computer (word) is the amount of data;

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
