Voting for the Third Annual Sphere XO Student Design Challenge Closing Feb. 27

Voting for the Third Annual Sphere XO Student Design Challenge is now open! You can help select which Clark County School District student’s design will be displayed on the ExoSphere, the world’s largest LED screen.  

The theme for this year was based around Pi Day, inviting students to think creatively about the intersection of art and science which are the same principles that helped design the Sphere. 

Voting begins Thursday, February 5, and closes Friday, February 27, at 11:59 p.m. PT. The winner will have their artwork displayed on the Exosphere on Wednesday, March 11, 2026, just ahead of Pi Day. 

Support our students and vote daily for your favorite artwork at thesphere.com/vote. Voting terms apply.
