Keeping the Iowa "wave" alive, even after the football season ends.
An Iowa man does something unique in Iowa City this weekend.
Rik Zortman's become known as the "Human Etch A Sketch."
He's from Avoca, Iowa. Rik sadly lost his son Armstrong to cancer back in 2009.
Armstrong was just three when he died.
But Rik keeps his son's memory alive by running.
Rik runs to map out the names of kids that are either battling cancer or have battled cancer. He uses an app called "Map My Run" to do this.
This weekend, Rik decided to try something a little different. He mapped out the name "Wave" in Iowa City on Gameday.
The word "wave" honors a new tradition this year in Iowa City, where fans at Kinnick Stadium turn around and wave at the people in the new children's hospital.
Rik says he decided to do this because he knows what some of the parents at the children's hospital are going through.
"To be able to be in a fraternity of parents that have children fighting cancer, it's a fraternity we don't want to be in. For those of us who have lose kids, we can still reach out to those that are still fighting," Rik says.
Rik says he hopes children will see the word "wave" that he mapped out, and he hopes it will be a reminder that people are thinking of them and want them to keep fighting.
Last month, Rik mapped out 100 names in honor of Childhood Cancer Awareness Month.
