So do I stick my head into that glass-enclosed rectangular box? Will it fry my brain? Or will the damage show up in 20 years? Will my head come out looking like those primitive shrunken heads that repelled and fascinated me as a child?
I’ve volunteered to have my head 3-D printed, and am checking out the equipment at the State University of New York. As it turns out—great relief—I don’t have to stick my head into the box after all; that’s where the “printing” occurs, not the scanning.
The professor tells me to just sit upright and stay super still on a chair for a little over a minute, while his assistant uses a hand-held scanner—making several passes of the sides and top of my head and neck from about 30 inches away.
In a couple minutes, the glass box starts to make noise and comes alive. The “printing” begins. For the color of my little sculpted head, I’m given a choice of red or white. Red seems a bit creepy, so I go for white. The plastic substance is long and cord-like, about 1/8 inch in diameter, and wrapped around a big spool at the back of the printer. One thin white layer after the other is laid down. It builds up, and slowly a tiny replica of my head begins to take shape. Half an hour, and it’s done.
Sure enough, this looks like a miniature Roxie, about 2 inches high, with a flat back where it lay down on the printer, although the machine appeared to have quit just before it reached the tip of my nose, which is kind of cut off.
So what can be done with this new kind of printing? Well, it is already being used in dentistry for making crowns. Jewelry can be created from metals, even gold. You can actually make plastic guns using this method. Unfortunately (or should I say fortunately), they don’t work very well—the plastic gets distorted rapidly from the heat and action of shooting a bullet.
But maybe the most fun is making food. Nursing homes in Germany are taking pureed food and making it into appetizing shapes. NASA is researching making 3-D pizza in space. Instead of white plastic maybe I should have asked for chocolate—and turned myself into a delicious dessert.
Roxie and her mini-me.

Using works from the National Gallery of Art by Vincent Van Gogh, Mary Cassatt, Edward Hopper, and others, Roxie Munro has created an innovative introduction to art. As an artist contemplates her next painting, she introduces genres and subjects, showcasing reproductions of great works. The sweeping painting she creates cleverly incorporates all 37 pieces she has considered.

St. Paul's Cathedral during the blitz of World War II.
When I interview people in my work as a writer, I soak up the stories they share about their lives. This is what brings history alive. I’ve always wished for a way to interview historic buildings, because they could tell stories from such a different perspective, having seen it all and heard it all. My dream interview would be St. Paul’s Cathedral in London, a place rich with history—and therefore, with stories.
I have learned that those with the most to say can be wary of interviewers. Sometimes employing a little charm can help them warm up. So I would begin by complimenting St. Paul’s on how wonderful it looks for a building that opened in 1708. I would reference its great architect, Christopher Wren, who was also an astronomer and mathematician, as is evidenced in many of its design elements. I’d mention its magnificent dome and its massive booming bells that can be heard for miles.
“You’re the prize jewel in a city rich in architectural beauty,” I’d say. “No wonder so many notables have been baptized, married, and had their funerals here.”
Flattered but still reserved, St. Paul’s might ask me what I like best about it. “I have two favorites,” I would reply earnestly, mentioning first the Crypt, where many of England’s war heroes are buried, along with famous painters and poets. (Writers and composers are at nearby Westminster Abbey). Other notables, like Florence Nightingale and Lawrence of Arabia, are here, too. It’s altogether quite a congenial place.
Starting to thaw a bit, St. Paul’s might wonder aloud about my second favorite, and I would single out the American Memorial Chapel, located behind the High Altar and dedicated to the memory of the 28,000 Americans who died defending England in World War II.
“And speaking of that war,” I would tell St. Paul’s, “I am awed by Londoners’ resolve that you, their national treasure, would not be destroyed during the Blitz when so much of the city burned. Volunteer firefighters, both men and women, were stationed at all times on your roof. When bombs exploded, starting fires, they were right there to put them out, a number of them sacrificing their lives.”
St. Paul’s would nod, remembering.
“The British love you very much,” I would say.
St. Paul’s would pause, clear its throat, and then reply, “Let me tell you some of my stories.”
