A Pennsylvania art installation had to be temporarily shut down after three visitors exhibited "seizure-like symptoms."
The exhibition was described as "intense stroboscopic light in combination with thick artificial fog, resulting in a loss of spatial orientation," the Daily Mail reported.
The artist behind the seizure-causing exhibit was Kurt Hentschläger, who specializes in " time-based media, light and sound," according to his website.
His art works to "reflect on the metaphor of the sublime and the human condition in the 21st century."
Patrons were asked to sign a waiver before entering the installation; those suffering from epilepsy, migraines, breathing problems, heart problems, and a number of other conditions were urged not to go inside of the exhibit. On Sunday an 18-year-old woman had to be treated at the scene of the exhibit.
"'You don't even know where you are, you lose your sense of space, time and motion," a patron told the Daily Mail.
In the installation, called "Zee," patrons walk around in a densely fog-filled room, there is an "ambient but minimal" soundscape and pulse lights, the Daily Mail reported.
Pittsburgh EMS claimed to have been to the scene on three separate occasions over the weekend, each case was seizure related, CBS Pittsburgh reported.
The other two patients had to be treated at the hospital.
Doctor's said the strobe lights were most likely to be the culprit in the incidents.
"Sometimes it may start out as smaller twitches. They may have twitches of the face, twitches of the arm." Doctor James Valeriano told CBS. "But that will go on to a big seizure like you really think of an epileptic convulsion."
The Pittsburgh Cultural Trust has made very few comments on the incidents, but said they were shutting down the installation temporarily until the situation was assessed.
"We are closing the exhibit indefinitely," the Cultural Trust said, the installation was originally set to run until Oct. 27.
"It did feel a bit like death. if you don't have a body, is this what your existence is like?" Another customer told the Daily Mail.
