drawTown
This sketch builds off of the drawHouse example:
  
     drawHouse
  
  
    drawHouse
  
  Create a function that draws a house.
 
This sketch defines a drawTown() function that calls the drawBlock() function four times, and the drawBlock() function calls the drawHouse() function four times.

Remix Ideas
  - Add some variety: give every house a random color.
- Make some of the houses skyscrapers, or schools, or gardens.
- Try different patterns: maybe your block only has 3 houses, or maybe your town has 6 blocks.
