Kinda of related, but not the same use-case it seems activated bursts versus my passive running.

Anyway. I'm doing something similar using cron, imagesnap and some ImageMagick [0]. It takes a screenshot, a webcam-snap and puts them together every hour into an image like this: http://imgur.com/JjUK0Rb

I tried with only screenshots and only webcam at first but the context felt lost so this was the end result. Pretty fun to look back at every now and then. I've had it running for something like 4 months now.

I wrote a program like this which is still in development... albeit a bit slow atm. https://etopian.com/software/automatic-screenshots-windows-m...

Looks interesting. Is there any video example of this?

It has a bunch of features, but it includes auto capture (both full screen and region only)
