Cell phone photo of a whiteboard doodle. The board is my brother's, the title is a sticker on the board, and my phone's camera isn't a selling point.

Dry-erase doesn't really work as a picture medium. Several times, the marker peeled a dried line off the board. And this drying phenomenon also meant I couldn't retrace just part of a line; not that it would have shown here, but there were gaps at the ends of any retraced section.
