Not sure how large your box is or just how small of pulls you need but, here is an idea I used on a box I built.
It is part of a golf tee. Just drill an hole of proper size in the drawer front, glue in the tee, and trim on the inside for length.
If he laminated boards such that the carving revealed a 3d topographical surface of multiple colors that would be cool. For example, a very white wood like holly or maple for the oceans and mountain tops and shades of brown/red in between. At least then it combines old school craftsman ship with technology.
I have respect for computer design and manufacturing - just not a lot of interest in it.
I actually think it's great on a technological level. Reminds me of those old birthday card maker machines, I used to see when I was a kid, that would draw it out right in front of you. Just doesn't do anything for me on the woodworking front.
All you see is the CNC running on its own. What you don't see is the craftsmanship behind the design and many many many hours of work programming it to run that specific function.
The beauty of CNC is repeatability though. He could literally make another map like that in as little as carving time of the machine. Doing that by hand will be near impossible.
