To Do:

1. Place the plastic shapes on the light table.
2. Look at the large screen.
3. Move the shapes into different patterns or add more
   shapes.
4. Notice what happens on the screen.

Explanation:

A camera system captures images of the shapes on the table, and where you placed them. A computer program creates the kaleidoscope effect. A projector then shines this effect onto the screen.

Application:

The kaleidoscope was invented around 1816 and made with a tube, mirrors and pieces of colored glass. At a height of 60 feet, the world’s largest kaleidoscope is located at a Catskills New York resort.
