As you would probably know the IAU doesn't define the stick figure shapes that help in navigating the stars within a constellation. The IAU only define the boundaries.
In fact, it can get pretty confusing navigating a constellation when people use "non-traditional" stick figure shapes. Wil Tirion pretty much defined a particular set of these "traditional" constellation figures over a period of forty years or more. His Stars and Planets of 1984 had stick figures for every constellation. I have just about worn out the third edition printed in 2000.
You could say he pretty much created a norm for these stick figures, which have been adopted by many other people and published in many astronomy books/atlases e.g. by the famous Patrick Moore (Philips Guide to Stars and Planets) and our own Massey and Quirk (Atlas of the Southern Night Sky).
As another example, SkySafari's stick figures are also very similar to his.
