Britain's Got Talent 's auditionee Johannes Stoetter captured the imagination of the judges and viewers alike on Saturday's show.
The Italian artist used live models who danced around on stage, explaining in a stunning performance a very important message.
The act was about the issue of ocean pollution and the heartbreaking facts about where the planet is headed had a clear impact on the judges.
Simon Cowell, David Walliams, Alesha Dixon and Amanda Holden watched in awe before sending the incredible act through to the next round.
A voiceover told the audience how precious our planet was, and how we need to take better care of it.
What looked like whales and a jellyfish were visible on stage, but as they began to move, the audience gasped as they realised it was a person.
A nude dancer painted to look like a giant sea turtle moved around on stage as the voiceover explained they were nearly extinct.
The whale unravelled and it was revealed to be a woman in blue body paint as the voiceover explained the effect global warming has on whales.
Learning that by the year 2050, there may be more plastic in the ocean than fish, Alesha said: "It's heartbreaking isn't it."
On the screen at the end read a message: "The future depends on us."
The artist then walked on stage along with his dancers, who had grabbed black robes to cover themselves with, and they bowed on stage.
Singer Belinda Davids also impressed the judges and the audience with her incredible rendition of One Moment In Time.
“What a way to end the show,” Simon said.
“This was just a fantastic end to a fantastic tour, I absolutely adore you.”
"You’ve created such a massive moment tonight for all of us," added David,
Alesha told her: “I want to see the name Belinda Davids in lights – you are amazing.”
