Six rooms, 20-30 seconds to take the ultimate selfie in each. This is one of the rules (minus the selfie reference) for Yayoi Kasama’s Infinity Mirrors installation, which has met with unprecedented demand for its upcoming Toronto exhibition in March.

Art Gallery of Ontario (AGO) members have expressed frustration over online ticketing, which left many members waiting for up to 10 hours in queue.

“It feels like we’ve been selling tickets for an Adele concert,” said Lisa Clements, the AGO’s Chief of Communications and Brand, to the Toronto Star. “We’ve never experienced anything like this before… really, this is unprecedented.”

The AGO’s ticketing system can normally handle up to 1,500 ticket sales an hour, but on the first day of its members-only sales, 18,000 people signed in to reserve their ticket. A total of 60,000 tickets are available, split equally between members and the general public.

Infinity Mirrors sells out in NYC, D.C. & L.A.

Kusama’s previous Infinity Mirrors tours in New York City, Washington, D.C and Los Angeles all sold out within a day or two.

The 88-year-old Japanese artist has been creating experiential infinity mirror rooms since 1965, and the current travelling exhibition presents six of them, the most ever shown together. According to the artist, the rooms provide an opportunity to celebrate “life and its aftermath.”

Strict time limits for visitors

Due to the nature of the spaces, up to four people at a time can enter each room, for 20-30 seconds at a time.

A full-priced adult ticket for the upcoming AGO exhibition costs $30, which equates to a cost of $10 a minute to view Infinity Mirrors.

Ticket holders should also expect to wait about 20 minutes to enter each room.
