6 p.m. Thursday, Oct. 17, Glenn Miller Ballroom, UMC Christo, an internationally renowned artist, will present a lecture on two works in progress: "Over The River," proposed temporary work of art that will suspend 5.9 miles of silvery, luminous fabric panels high above the Arkansas River in south-central Colorado. "The Mastaba," a project for Abu Dhabi, will be the largest sculpture in the world, made from 410,000 multi-colored barrels to form a mosaic of bright sparkling colors, echoing Islamic architecture.
