It is said, especially in constructive art, that “less is more”. The ideal would be a simple, strong, shape, well made and of interesting construction. For the past forty years I have been trying to make such work, but I still struggle with contradictory considerations: leaving things out (like surfaces) can lead to objects which do not look simpler, but, on the contrary, more complex. Presenting a geometrical idea in a beautiful way sits in the way of presenting it in an understandable way. These days, I notice that considerations of ‘beauty’ are of less concern to me than they used to be; it is the geometrical idea, the play with newly discovered ratios, which takes precedence.
