Well I just finished a first working versions of mooslides, a sliding panel widget for mootools. It was inspired by all those sites (gamespot, tv.com etc.) using flash sliding panel widgets. I’m pretty sure a similar widget already exists for mootools, haven’t looked actually, but eh it had been a while since I had some fun with mootools and I wanted to try out the new 1.2 version.
An example can be seen here:

This one is using images but you can pretty much put anything you want in the panels (images, text, form etc.).
