If you're a regular listener to just about any podcast on the planet, then you've probably heard of Fracture. They've been advertising for a long time on many prominent podcasts I listen to, and Marco Arment is well known (within the Apple developer community) to have used Fracture to make physical icons that he can hang on the wall of his apps. Fracture is a service that prints your digital images directly on glass. No need for framing or matting - the print comes with a backing that allows you to hang it on the wall without a frame. Oh, and they look beautiful.
Several weeks ago, I finally bit the bullet and committed to buying a Fracture print for myself. For my first Fracture, I chose an old map of the Roman Empire that was made in 1811 by William Darton, a London English cartographer. I found a wonderfully high resolution version of this map using the David Rumsey Map Collection which is a wonderful database of very old maps. I have no idea the exact time period this map depicts, but based on the map itself, it would be somewhere in the late 1st century or early to middle 2nd century.
If you like the idea of a Fracture and want to order one for yourself, they gave me a coupon code you can use for 5$ off.
Here are some more pictures of the print I had made:
