photo trick
I thought I was going to have to post the "dunce" picture again, but I realized at the last minute that I had indeed snapped a picture today. Although it's nothing exciting, this picture illustrates a neat trick you can do with your point-and-shoot or phone camera. I was in the [amazingly confusing] parking deck at UNC-CH, so I snapped a picture of the signage to help remember where I parked.
