Enhancements for moving displays in general, and in particular, dynamic signage and kinetic sculpture. More specifically, the present invention relates to improvements on moving banners (18) for use within entertainment, advertising, signage, art, theater, performance visual instruments, and attraction contexts. Improvements are cost-saving computer controlled torque friction brakes (16), substantially inelastic reinforcing cable (20) to allow elastic banners (18) to handle relatively higher wind loads, and reusable removable printed image banner sleeves (22).
