It was a truly moving piece of art.

A giant white orb — which is part of a Nuit Blanche exhibit in Nathan Phillips Square — came unmoored this week.

“High winds did cause the balloon, which had been installed earlier in the week, to come unmoored. It was tethered very carefully but the winds were very high,” said Michael Prokopow, a curator of the all-night art festival.

The balloon — designed by Director X, the Toronto music-video director behind Drake’s “Hotline Bling” — was damaged when it broke free from its restraints.

“There was great concern and upset,” said Prokopow, who is also a professor at the Ontario College of Art and Design.

But Nuit Blanche attendees will still get to see the exhibit. A new balloon will be put up Saturday morning, as soon as the high winds die down, Prokopow said. He added that the new installation will be “undamaged and uncompromised in any way.”

The sphere will be part of Director X’s project “Death of the Sun” during the all-night artistic and cultural festival Saturday.

Director X — born Julien Lutz — said in a statement that the piece “is intended to portray the death of the star that sustains us.”

“Although we all know that our earth is a tiny little rock in comparison to our sun, a true comprehension of this immense reality is difficult to grasp,” the director said on the Nuit Blanche website.

The exhibit is part of “Oblivion,” a larger 3-part project curated by Prokopow and Janine Marchessault.

“Ultimately Nuit Blanche is about bringing visionary, powerful art to the public and in that work you like to think everything’s going to go as planned but you’re always prepared for things that go unexpectedly and I think that’s what we have here,” Prokopow said. “But when the art is up, people will be seduced.”
