CS-105 Lab 2: Line Art Animation

CS 105 Introduction to Computer Programming using JavaScript 
 
Lab 2: Line Art Animation 
 
On the class website, there are 6 example line art programs listed at the end of week 6. Run 
them and make sure you understand them. Ask for help if you cannot understand them.  
Your task is to make your own Line Art program. You may use any of the code given on the 
website, but you must modify it so that is looks very different from what I made.  
 
Grading Rubric [20 points total]: 
[Turn in: 2 points]: Your .html file is correctly attached in Blackboard learn 
under lab 2 with the correct file name: 
LineArt_yourFirstName.yourLastName.html 
[Too Much Like the Given:  -20 points]: Turn in one of the example programs 
with only minor edits if you want a 0 for the lab.  
[Lots of Things: 4 points]: When your file is opened in the Chrome browser, 
with  processing.min.js in the same directory, your program draws at least 
200 different lines (and/or rectangles and/or ovals) per second.   
[Lots of Colors: 4 points]: Whatever shapes your program draws after no more 
than a minute includes at least 200 different colors.  
[Animation: 5 points]: As your program runs, something is always changing at 60 
frames per second. 
[Niceness: 5 points]: The overall effect you create is pleasing to watch. Do the 
patterns you draw look cool? Do the colors look nice together? If you are 
colorblind, then stick to shades of gray (red, blue and green each having 
equal values – there are 256 different shades of gray in JavaScript) or ask 
someone who is not colorblind to tell you if your colors are horrid and painful 
to look upon.  NOTE: you only qualify for getting these points if you get all 
points in “Lots of Lines”, “Lots of Colors” and “Animation”.  
[Extra Credit Super Awesomeness: up to +10]: When you show your friends and 
family what you created, they all say something to the effect of “that is 
awesome”! Let me know about it, demo it in class and get some extra points.
