The Doppler Effect
is a very unique member of our modern metal art collection because unlike many of Nicholas' sculptures the grind pattern does not cover the entire surface. It is in one isolated path traveling from one edge the other. Nicholas has to be so careful when grinding this sculpture because the edges of the winding pattern are actually outlined first by hand with a blade After that is completed, he meticulously grinds the metal, also by hand, within the outlined path.
The squiggly grind trail of this sculpture looks very much like an aerial view of a winding river. This sculpture looks beautiful unpainted as well, as you can see from the original 'Doppler Effect'
