For the past 14 years Tulsa has celebrated the American art form of art cars. On Sunday, kids in Tulsa got the chance to create their own Box Art Cars.
There are no rules - anything the kids come up with, they try to create.
"It's been fun," said Charlie Larson, one of the organizers.
"We have a tank; we have a monster; we've had a rocket ship, a pink flamingo - it goes on and on. There are things that defy description."
Next weekend the kids will get to show off their creations during the Box Parade at the Blue Dome Arts Festival. Organizers weren't sure exactly how many kids attended, but they made about 400 boxes.
