"It started out as a scrapbook... and then it just kind of mutated!"—Chloe Sullivan
The Wall of Weird was a mural, and later either a computer program or a website, as it was accessed on a computer, made by Chloe Sullivan of all the strange and bizarre things that happened as the result of the 1989 meteor shower.
The Wall of Weird was a collage made up of clipped magazine and newspaper articles.
The Wall of Weird started out as a scrapbook that Chloe Sullivan kept but she eventually began to hang the articles up in the darkroom of the Torch office. Eventually, she moved it to the wall of the classroom that served as the office of the Torch.
The Wall of Weird contained the cover of infamous Time Magazine issue featuring the anguished cry of a three-year-old Lana Lang on the day of the meteor shower. While Lana hated the fact that she was on the wall, she never asked Chloe to take her picture down. When Clark Kent first saw the wall, he became upset because he felt he was responsible the meteor shower and all of its adverse effects.
Chloe took the wall down for good when she graduated from high school, but set up a miniature version of it in her dorm room at Metropolis University. Her roomate hated the wall and tried to take it down, but was stopped by Chloe. After Lana became a vampire, the roomate moved to a different college and Lana took her place as Chloe's roomate. It can be assumed that Lana had no problem with the wall and it remained up until Chloe left the Unversity. (Thirst)
The Wall of Weird is seen without the pictures and articles when Clark returns to the High School for a reunion. However two young reporters, Zoe and Clayton, then explain that they have taken up the Wall of Weird legacy and it is now viral. (Homecoming)

- Pete: (to Chloe) I think you ought to show him.
- Clark: Show me what?
- Chloe: It started out as a scrapbook and just kind of mutated.
- Clark: What is it?
- Chloe: I call it the Wall of Weird. It's every strange, bizarre, and unexplained event that's happened in Smallville since the meteor shower. That's when it all began -- when the town went schizo. So what do you think?
- Clark: Why didn't you tell me about this?
- Chloe: Do you tell me everything that happens in your life? We all keep secrets, Clark.
- Clark: Lana? My fault. It's all my fault.
