Walking Through Mirrors

I've always been fascinated with mirrors

I remember when I was a kid getting a haircut in a barbershop of seeing my image in the mirror-- as well as the reflected image of my back in the mirror behind me, and seeing the image within that, plus the image before that, and the image behind that...

I always wondered how it would take if I were to step into the mirror before me to exit at the mirror behind me. Forever? Instantaneous?

So it's no surprise I was reminded of this when I saw this website about cats watching cats watching cats watching... ad finitum to the 275th cat.

The mind boggles.
