Sketchcast. ‘Sketchcasting is a new way to communicate something online by recording a sketch, optionally with your voice speaking. Any sketch can then be embedded on your blog/ homepage for people to play-back, and you can also point people to your sketchcast channel here (or let them subscribe to your sketchcast RSS feed).
Sketchcast is new but it’s based on an old principle: the whiteboard (or the napkin in a bar) on which you sketch something to get a concept across… or to just have some fun. Sketchasting was invented by Richard Ziade on July 23rd, 2007.
