Here's one from the way-back machine. My friend's little sister was visiting Chicago with him in 2006. I stumbled across the image when I was looking through an unkempt folder of pictures. I like this because it's the moment she stopped hamming it up.
For the camera nerds, this was captured with a Kodak/Canon DCS520, one of the first digital SLRs. Only 2 megapixel, but shockingly good image quality if there's enough light. Kodak built a digital rig into a Canon 1N film body; it's a behemoth.
