It was really magical stuff. I don't normally bother with things that have timed entrances and long lines but it was so worth it to get to go inside a few Infinity Mirror Rooms. The AGO acquired one of them after the exhibition, so there is a lot more opportunities for people in the area to experience it.
Yay for kids in galleries! I'll take a few rambunctious kids over some know-it-all offering unsolicited interpretation to strangers any day.
