This video gives a good explanation of the mathematics behind shear transformations, but I'm still not sure if I intuitively understand what's going on in a shear transformation. Is there a simple analogy/explanation of what shear transformation is?

"A transformation in which all points along a given line L remain fixed while other points are shifted parallel to L by a distance proportional to their perpendicular distance from L." Check the link below, it also has an image that helps understand the definition they provided.
