Square Coffee Cups

SSS,

One again science has proven your remarkable insight correct.  Round cups add to the spillage while walking so go with a different shape.

But the best way to prevent coffee spilling might be to find an unusual cup. According to Krechetnikov, ideas from liquid sloshing engineering studies, which historically were done to stabilize fuel tanks inside missiles, indicate three possibilities for spill-free cup designs: "a flexible container to act as a sloshing absorber in suppressing liquid oscillations, a series of annular ring baffles arranged around the inner wall of the container to achieve sloshing suppression, or a different shape cup."

Same theory behind a stemless wine glass. I don't know about coffee.

I've found you don't spill much if you nurse straight outta the bag.
