Consumer obsessions

Consumption, consumption, what's your function? Kate Bingaman-Burt has been asking herself — and, by extension, all of us — what's the deal with consumer consumption for the better part of the 21st century.

She began documenting every single little purchase of hers as a grad student, and she's turned this obsession into an art form.

Even now, while Bingaman-Burt is a graphic design professor, her Obsessive Consumption blog still features daily buys. She also creates art installations about consumerism and writes for various publications.

Learn why she started sketching her credit card statements and what she's discovered most people spend money on in an interview with the woman behind Obsessive Consumption on Yahoo! Picks Profiles.
