Ripper is an application that periodically grabs online images to create timelapse movies. Pictures are ripped off a specified website every few seconds, minutes or hours (whatever the user decides), then they are merged together as frames in a time-lapse video. Some cool effects can be achieved this way.

There is now a Google Group for Ripper where anything and everything to do with this software can be discussed.
