I really do like some of David Mach's sculptures, Have you seen them? They are quite fantastic. 
They are stunning. His work is based on mass-produced objects in flowing assemblages
Yes I just love that about him, He has some gigantic sculptures as well. How old is David anyways? 
He was born on March 18, 1956 in Scotland
Oh wow so hes not too old, Do you have a favorite sculpture by David? 
Polaris was one of his early influential sculptures. It was outside the Royal Festival Hall in London in 1983.
