I'd put a darker colored design on it, close to the color of the wallet. The disk design would look really sweet too.

Make a Bionicle parody of the Harvard logo and emboss it.

The design is gonna be lasered on so I don't really have a choice of color there, more that I wanted opinions on whether I should choose a design that's associated with darker colors like Vakama or something more generic like the three virtues symbol.
