Just 2x2 tiles and 1x2 plates. You can also use 2x2 plates, but then you end up with a lot of pressure and the base plate will bend - in fact I used plates here and you can see that it bends. You will get a cleaner and smoother look with less gaps when using tiles - I just hadn't the parts to do it right.
This technique will give you a quite irregular and complex look.
