I think it would be way cool to have a video that showed you aging. Something similar to this, but a LOT longer. The problem with all the videos I see on youtube is that they’re over short periods of time like 3-6 years, or the videos are so long that you can’t see any aging taking place. Most of us don’t look that different after a few years, but over decades of course there are big changes. Someone needs to compress 30-50 years of pictures down to 1 minute of video. That would be awesome.

Biggest problem I see is that you need a dedicated space to sit/stand every time you take the picture, and you need a dedicated tripod and camera. The above link is really well done in terms of her head not moving.

30-50 years is an awful long committment though.
