I frequently lose my Buck-ID (OSU's student ID) and have had to get new ones probably 6 times in the last year and a half. Anyway, someone found my old one and returned it to me, so I was able to compare, and I'm very happy with the changes.
As you can tell by the paleness of my skin, the second one is this winter (Jan) and the first one is from this summer...July or August, I believe.
Sorry about the picture quality, I took this pic on my webcam.
*edit* I'm putting up a slightly better quality pic.
