    * {{ lecture6.pdf |}} Code: {{ lec6.rkt |}} \\ \\ 

  * Assignment 2:
    * Happy Cat -- //to come//
    * demo
    * gist: 
      * this assignment combines both parts of assignment 1 into one big-bang program
      * one additional difference: the cat moves left-to-right and right-to-left at different times, changing direction when it hits a wall (instead of wrapping around)
      * we can no longer represent the state of the world with just a single number
      * this big-bang program uses a structure to represent the state of the world
      * the state of the world keeps track of the cat's x coordinate, the cat's direction (dx), and the cat's percent of happiness. 
    * templates for vcat functions: {{ vcat-template.rkt |}}
    * due: Monday, Mar 29 \\ \\
