There is, for instance, his Untitled of 1964 that also has the colloquial title of ‘Swimming Pool’. This sculpture is of a square configuration resting on the floor. Consistent with its square configuration it has straight sides, but the corners do not intersect at right angles, instead they are round. Inevitably this gives rise to the contrast between straight and round, as in the sides and corners respectively. Meanwhile his wall relief constructions consist of parts, that in their horizontal orientation relate to one another through a positioning often based on the Fibonacci series, some of these later pieces even.
