Airport art

There is a fascinating exhibit in the Atlanta international airport terminal composed entirely of business cards. Covering a wall nearly the length of a football field, it reads, "Let each man pass his days in that endeavor wherein his gift is greatest" - Propertus. I've never heard of Propertus, but he sounds like an ancient Roman with a universal prayer, the desire of all of us to do the work for which we are suited, something that fits us and that which we enjoy. Clever was the artist (don't know who) who came up with the idea of making the quotation in business cards. I'm only showing a tiny portion here -- and the original is across the wall, panoramic style -- but you'll get the idea.
