As I remarked to him, I wish I had the technical knowledge and the time to figure out how to automatically generate similar images from my Mint stats.
As it was, I’ve been trying to track my daily subway commute, which you can see at Daily Transit by hand using Adobe Illustrator. It seems to me an iPhone app plus some script ninjas could automate this for me.
