I especially love her blog, where she draws and posts her daily purchases. Earlier projects included taking pictures of all purchases, drawing receipts and drawing credit card bills. (You can also buy the design professor’s drawings compiled in zine form at her Etsy store.)
I’ve been a fan of Kate Bingaman-Burt’s for quite a while (since before she added the -Burt!). Back when I was in college, I interviewed her for a zine I did on consumerism (its second issue is still unrealized) and she keeps popping up on my radar. Bingaman-Burt’s site, Obsessive Consumption, has changed multiple times since my college days, and it’s still interesting to dig around in.
