It is hard to miss the eye-catching work of famed sculptor Hans Van de Bovenkamp as you make the walk through the pedestrian tunnel connecting the transit center and the light-rail station. The 8-foot red aluminum free-form structure in the shape of an "O" appears to be alive, undulating, seeming to change shapes as the sun hits it from different angles during the day. The sculpture is a variation on a theme called "Gateway" that was erected in Oklahoma City's Myriad Gardens in 1993. Just because it is in the hellhole that is Oklahoma City, don't hold that against ol' Hans.
