Focus on this artwork and explain the Features.
The Open Hand sculpture is 26 metres (85 ft) high above a trench of 12.5 by 9 metres (41 ft × 30 ft). The metal wind vane, which is erected over a concrete platform, is 14 metres (46 ft) in height and weighs 50 tons; it appears like a flying bird. The sculpture was hand-cast in sheet metal at the Bhakra Nangal Management Board's workshop at Nangal. The surface of the vane is covered with polished steel and is fitted over a steel shaft with ball bearings to facilitate free rotation by the wind.
