As far as I know it’s just cardboard, wood and glass
In: Physics
The crucial parts are 3 or more mirrors and colored beads.
The mirrors are all facing each other, so they’re reflecting off each other making anything inside them look more complex. The reflections are being reflected, the reflections of the reflections are being reflected, and so on.
The colored beads are being reflected by the mirrors, so they look far more complicated than they really are.
Cardboard, glass, and mirrors! They make a tunnel out of mirrors – usually three to form a triangle–then either allow you to see through it or put a membrane over the other end to scatter light and fill it with colorful beads so you get a bunch of colors instead.
When you look down the tunnel of mirrors, you see the strange patterns of the fractal reflections it creates into infinity (or as far as it can go) from all the light then bouncing around inside the scope and rerererere-reflecting the same image over and over again.
Oh ok. That makes sense, thank you
