It's also more of a metatagged animation format than a video format. The reason they can get sizes down so much is because they store mouse pointer *movements* instead of the actual draw/erase/redraw of the pointer, then overlay the pointer. Same goes for window movements. If you're familiar with VNC (more specifically, UltraVNC), it's the same principle which enables remote-control of a desktop over a modem. -- Jim Leonard ([email protected]) http://www.oldskool.org/ Want to help an ambitious games project? http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
