What's x11rec?

x11rec is a very ad hoc X11 recorder which creates a movie. x11rec sequentially runs xwd to capture a sequence of window images and finally creates a movie file in an MNG or animated GIF format with ImageMagick and Gifsicle

Sample movie which records gnomine (22 sec., 14.5 fps): MNG (66 KB), GIF (38 KB)
