The use of color and arrows are nicely done.  The program would work well in a high school setting, but may not be sophisticated enough for a university level class.

The videos seem fairly nice, however at times the presenters are careless with mathematical ideas and notation.

This page specific in nature.  Using JavaScript, it generates a random nonsingular 3-by-3 linear system.  The corresponidng augmented matrix is populated from the system, and the user is

This applet provides a simple interface to enter the coefficients of a linear system of equations.  The applet implements a number of different solutions methods: Naive (Gaussian and back subs

This page provides a demonstration to help students visualize transformations and mappings used to move (rotating, reflecting, translating), resize (contracting, expanding), and reshape (shearing,

This page provides an introduction to reversal matrices, which are obtained by writing the rows (or columns) of an indentity matrix in reverse order.  The page the outlines how to generate rev
