Heres my first pattern from the first studio. Its the one we had to draw in the first lecture.

The main draw code is:

line(0,0,50,0);
line(50,0,50,50);
line(50,50,50,100);

with the x and y moving 50 and 100 each time respectively.

Its relatively simple but it was just to understand the program initially.
