Accounting is all about debits and credits, and the fact that the two are always equal (at least they are if you do it correctly!). With that in mind, I would look for a two-color quilt with equal amounts of the two colors. The most obvious that I can think of is Robbing Peter to Pay Paul, but that has lots of curves, which I personally would not attempt. There is also Hunter's Star, or a four piece Rail Fence. Positive/negative versions of most any block will get you the same result. Another advantage to this approach is that if he changes majors it doesn't scream Accountant. BTW, I am also an Accountant. ;-)

P.S. I just went and did a search. Kaleidoscope, Winding Ways, Jacob's Ladder, and Jewel Box would also work.
