Here’s a great conversation piece that any photographer should appreciate. Even non-photographers will want to keep track of the date with this Camera Lens Calendar. It beats those boring paper calendars. Just adjust the focus rings until the current day and date are aligned.

It’s from the mind of designer Sharad Haksar and believe it or not it’s already headed to stores, but there’s no info on price. I’m sure it will be a hit. Then he can make one that’s powered and snaps pics for visual reminders that you need on a calendar. It could display such pics on the camera side of the lens.
