If you open the .ps file in a text editor, you'll notice that it's hand-written and has a neatly tweakable table of spells at the end, after the layout code for them. It also makes the recursive shield heraldry recursively.
The comment in the code says it's called recursively, but it looks to me like it's just called iteratively 10 times in a `repeat` loop. Unless it's "recursive" in that each iteration seems to resize but keep the previous?
