LICEcap
simple animated screen captures
LICEcap can capture an area of your desktop and save it directly to .GIF (for viewing in web browsers, etc) or .LCF (see below).
LICEcap is an intuitive but flexible application (for Windows and now OSX), that is designed to be lightweight and function with high performance.
