This is an incredibly neat little widget I stumbled across today. It's only been live for about a month now so I figured it was worth a little write-up.
"ThatsMyMouse" is a tool that allows users on your site to see not just their own cursors, but the location of anyone else's cursor who happens to be browsing the site simultaneously! Users have the option of enabling or disabling ThatsMyMouse and are even able to chat with other users on the page via a little chat window and little word bubbles that appear above their cursor's marker. If a users cursor does not move for a certain amount of time the user will be designated as idle and the marker will show a little "zzzz." The novelty of it all is certainly fun. You can check it out for yourself with a little demo here:
I'm not really sure if this is actually something that will catch on. It brings to mind visions of popular sites cluttered with cursor markers, and I'm not sure how this would effect a sites performance. Of course there is always the option to turn it off, so if you don't want to see those cluttering markers you don't have too…
Something like this could perhaps have place if integrated with a network like digg or stumble upon. Sort of a "real time tagging" sort of thing. I'm interested how you guys think this will fit into the web 2.0 trend, so throw out some comments if you've got an idea!
