Most of the things that surround us in our daily lives consist of infinitesimally varied geometric shapes, and this is also true in Carl Barks' duck universe. In the sub-pages you are presented to a number of examples divided into manageable main categories. Some of the examples may constitute simple dimensional problems, because Barks naturally drew his objects as two-dimensional objects, whereas we perceive known objects for what they really are by 'translating' them into three-dimensional objects. Thus, you will have no trouble in perceiving for example the drawing of a balloon as a totally round object instead of a flat disk.
