Two fairly similar services here, brought to my attention by the ever reliable TechCrunch.
Demofuse allows you to create ‘tours’ of your websites, to demonstrate functionality, say. It looks very useful indeed, and will be something I will be using for some of the services I’ve put together.
Screencast-o-Matic is a service that lets you create screencasts – that is, the recording of what happens on your PC screen – within the browser for free. Cool! Screencasts are great for recording demos of how to do stuff on the PC, whether online or not.
