This is a small addon that automatically and continuesly takes a screenshot every 30* minute. It can be altered to a more suitable duration, but I like the 30 minute mark.
The addon serves a single purpose for me, I'm nostalgic, and like to 'document' my gaming time. Random screenshots from the last 3½ years of my WoW career have been saved through addon functionality (I'm close to 8000 screens).
When i feel like it, i walk through the screens, and it takes me back to my glory days of MC, BWL, AQ20/40, ZQ, NAXX, KZ, ZA, PVP outdoor events, you name it, i probably have it saved.
I'm now offering the addon to others that may look for something like it.
* - To change the duration between screenshots, look in the lua file and change the variable called "delay"
