Animated mathematical figures

In an e teaching workshop organised by CII Shiksha, I got to know about a cool animation tool UnFREEz. The addition of this e software to my directory helped me to add life to still mathematical figures. I experimented with this software in creating some animated mathematical stuff.
Have a look.

The following three figures are created to explain the properties of a rectangle viz. both pairs of opposite sides of a rectangle are equal, each angle of a rectangle is a right angle and diagonals of a rectangle are equal.

The figure given below may be used to understand the concept of vertices of a cube. Observe the pink dots. My students were making mathematics project on optical illusion . I thought of creating animated illusions using UnFRRez. Two parallel lines turning into a pair of intersecting lines ... Two equal lines turning into unequal lines...
