Mondo Guerra, runner up of Project Runway season eight and the winner of Project Runway All Star, revealed a new art installation focusing around the changing face of HIV this weekend.

The installation ran at the 2016 United States Conference on AIDS (USCA) in Hollywood, Florida from Sept. 15 to 18.

Mondo revealed that he is HIV positive on an episode of Project Runway, and has served as an advocate since. He has been positive for the last fifteen years and strives for HIV treatment and overall awareness.

The installation, titled “Positivitree,” displays “yam-bombed” trees. They signify “courage, strength and the progress being made in medical science in HIV,” according to a press release.

Last year, Mondo participated in the 2015 conference, but not to present or perform. Instead, the Project Runway winner walked the floor, being noticed by both fans and people who had never heard of him.

“I apply a lot of that truth and honesty that I shared within my story to my work,” Mondo told The Washington Post at last year’s conference. “Working as an advocate has really improved my work as a designer. If you asked me 10 years ago what to expect I would never have expected all this.”
