Ripper is an application that periodically grabs online images to create time-lapse movies. (Nimisis.com also has software for making time lapse videos using your own webcam connected to your PC.) Pictures are taken from the specified online webcam every few seconds, minutes or hours (whatever the user decides), then they are merged together as frames in a time-lapse video. Some cool videos can be made this way. For example, do a time lapse of Loch Ness and get a pic of the famous Loch Ness Monster or timelapse the pyramids in Egypt.
