Lines 2

 

Rules:

1.  Use a random number generator from 1 to 10.
2.  Draw generated number of lines (in this case 4), each line shorter than the next.  (This group of progressively shorter lines will henceforth be called a "batch.")
3.  After drawing the generated number of lines, draw a new batch.
4.  Repeat until finished.
