Ultimately, Silverman created more than 400 metal sculptures, ranging from 60-foot stainless steel installations to creations just inches high. Many of them are based on the tetrahedron, a shape with four triangular faces.
His sculptures have been installed at more than 30 public buildings in the New Orleans area, including the Tulane Law School and the A.B. Freeman School of Business, East Jefferson General Hospital in Metairie, the Entergy Centre on Poydras Street and Temple Sinai on St. Charles Avenue.
