Screenjelly is a free web-based tool that allows anyone to quickly create a screencast video. To use Screenjelly all you need to do is go to Screenjelly.com and click the big red “record” button. Once clicked Screenjelly will begin recording your screen and your voice (if you choose) for up to three minutes. When you’re done recording press “stop” and you can then share your video on Twitter and other social networks. You can also embed your Screenjelly recording into your blog or website.
