    # You could continue this process for each leg, like in the original
    # example, but it's pretty silly to repeat any chunk of code so many times:

    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len 
    x = x + spacing
    line x, y, x, y + len
    
    # A nicer way is to repeat that chunk of code with a block,
    # you can see how in example 06.
