Linear transformation applet
View the action of a linear transformation on a two dimensional shape. Built-in shapes are the unit circle, unit square, and a star. The 2 by 2 matrix can is entered in a grid. Operations include roatation, reflections, scaling, stretch, shear, and projection. Information about the matrix is displayed. Composite "maps" can be executed.

Easy for students to use and experiment with compositions
Easy for students to use and experiment with compositions. The inclusion of matrix information along with preservation of geometric features is a novel idea.
very good
There's a typo. The transformation matrix is 2x2, not 4x4. Otherwise, very good.
