Planar Laminae
A plane lamina is a two-dimensional planar closed set with finite area. The concept of "area" is sometimes generalized to "mass" when a density function is associated with a lamina. Wolfram|Alpha can classify and visualize many laminae and compute their interesting properties, including multiple kinds of moment of inertia.
