This hinged pair of quilting mirrors is available from Amazon for $10.94. It is great for experimenting with kaleidoscopic images produced by a pair of mirrors.

There are several ways you can view 3D images. This pair of glasses is my personal favorite. It is used to view direct images and is available from Amazon for $30.95. Cheaper red-blue or red-cyan glasses for viewing anaglyphs are available at 50 for $9.89 from Amazon.

This is the Mirascope. It is available from Amazon for $10.99 and uses the power of parabolic mirrors to create a startling optical illusion. Parabolic mirrors are also used for deep space communication.
