While I did encounter a magnifying mirror this weekend, the results of my experiment were significantly less mind-unhinging than depicted in the comic. I’ve always liked the phenomenon of infinite mirrors, most commonly encountered near fancy dressing rooms. A lot of gyms and exercise spaces end up having mirrors positioned that result in the effect too. I tend to think of those dressing room areas first, though, most likely stemming from childhood boredom in clothing stores. I remember being a kid and jumping around in front of them, always trying to find a position from which I could get a clear view of myself receding into infinity, except that I could never really see past my own head, which was vexing. I still do that now, in fact– I’m just more self-conscious about it.
