Custom Glass Heart Map Necklace.
Soft Cities is a San Francisco-based company that sells blankets and napkins. There's something quite cool about these blankets and napkins. You can custom-print them to feature a street map of your favorite location, like a college campus, hometown, or far-away city. Working with Stamen Design, an award-winning tech-and-map design firm in the Bay area, it uses open-source software to access a kind of "world-wide Wikipedia for maps" and turns it into custom textiles of any neighborhood you want.
Take the outline of the campus or city/location and decorate it by writing in things you did there over the years.
