 Finding it difficult to transport large, heavy, welded pieces, he turned to angled sections and sheets of steel and aluminum that could be bolted together on site.Typically the pieces were painted with bright colors and the thin edges were often defined with bright, complementary colors (see "Long Distance","Chicksaw" or "Kobi").In the late 1970s, Kipp's steel sheets began to move into the air on thin legs (see "Lockport 1977", "Salute to Knowledge" or "Yoakum Jack").
