One of the great pleasures of each of my Tucson visits is to see what my friend Simon is up to with his public-art projects. For his current one, he and his creative partner Ben have come up with a poetry-based enhancement for the stops along the city’s new trolley system. Shelters will feature electronic displays that spell out poems by locals. And at the head of the line, this head, fashioned by thousands of Ben’s welded-together stainless-steel letters, that will “speak” a stream of more letters up into the back of one of the electronic displays. I can’t wait to see the final results of this work I had the pleasure of seeing in progress.
