Each time its home button is pressed an iPhone automatically takes a screenshot of the current app to display a zooming effect.

For this performance, I installed two shell scripts on my jailbroken iPhone:

1  The first one duplicates each screenshot so that the files cannot be overwritten the next time the app is minimized.

2  The second one uploads these screens automatically to this site and publishes them.

These scripts are executed regularly in the background by means of launch daemons.
