Gifshot is using the latest HTML5 technologies such as WebRTC getusermedia, filesystem, video, canvas, web workers and more, to build the animated gif file from media streams, selected videos or images.
I already tried in Firefox its really funny and easy. Download and unzip the files go into demo folder and open index.html, have fun!
