In this Demonstration the fingers are moved by applying affine transformations to their segments. An affine transformation consists of a linear transformation followed by adding a vector, in other words, multiply a variable vector by a given matrix and add another, constant vector. Affine transformations preserve collinearity, that is, points that are collinear continue to be so after the transformation.
