More recently at 7 World Trade Center there were constraints and requirements such as making the electronic wall blast proof, and this slowed me—constructively. I could think more about how the piece should look and about what content it should offer for this tragic but optimistically restored site.The newest complicated sculptural LED arrays require that I try to marry form, function, information, beauty, time, transcendence, realism, legibility, phantoms and more—and then make sure the stuff works. It’s routine for function or lack thereof to affect the look, for the look to demand better function, for the shape to change content, for the content to require different colors, for the programming to need more speed, and around we go. But I attend to what has failed in the course of the electronics and then use what has come to be right. Sometimes it’s a relief these days to make the silk-screened paintings that are relatively simple to produce.
