The Story Behind D.F. Miller’s Iconic Crossroads Sphere
10.12.2026
If you've ever walked through the Kansas City Crossroads, you've likely spotted the giant, spinning black ball outside the Freight House. Known officially as the "Rotary Sphere," this iconic landmark was created in the late 1990s by artist D.F. Miller (’80 Sculpture).
As a minimalist, Miller deliberately designed the piece without a strict meaning, letting locals playfully compare it to everything from a Poké Ball to a giant cake pop. The sphere was originally part of a larger push to bring art to the newly renovated train depot, alongside creative works by Jim Woodfill (Professor & William T. Kemper Chair of Painting) and Karen McCoy (Professor Emerita of Sculpture and Social Practice).
Almost three decades later, Miller's beloved sculpture is still spinning on its original motor after a recent tune-up. What started as a unique way to welcome visitors to nearby restaurants has grown into a genuine generational touchstone for the city. Miller loves hearing stories about Kansas Citians who took childhood photos in front of the sphere and are now returning to recreate those memories with their own kids.
