| Applet | Description |
| Geogebra Applet | This applet shows what reflections you get from three mirrors angled at each other. This interactive applet deminstrated what patterns are created if you move three objects around in front of the mirrors. This is exactly what happens in a kaleidoscope. |
| Physlet Physics | An interactive applet that shows you the light reflection off of two angled mirrors at different angles. |
| Resourses | Description |
| YouTube Video | This is a video demistrating and explaining image formation by two plane mirror at different angles. This concept is important for understanding how kaleidoscopes work. |
