Giant kaleidoscope

What can you do here
Step into the equilateral triangle formed by three mirrors. Observe the image created as a result of multiple light reflections. Examine how the image is changes as you are move.

How does it work
The image is a result of the light being reflected by three flat mirrors of the same size, according to the laws of reflection (the angle between the surface and incident ray and reflected ray stays the same). The image created this way is symmetric. 

Interesting facts
There is a notion that chambers with mirror-covered walls were used in the past as places for a sophisticated kind of torture – the incessant watching of infinite number of one’s reflections.
