Clutter is an open source project that has been around since 2005, and "marketing morons" have nothing to do with its name. and since it's an API to create applications, toolkits and desktop environment, then you won't have Clutter on your desktop, but your desktop will use Clutter internally.

oooh, it was a pun on the name! now, I get it.

actually, the fork of the Metacity window manager using Clutter to handle the scenegraph is called Mutter

a video? like, I don't know, this one? :-)

the Moblin 2.0 UI for netbooks is probably the best showcase of what Clutter can do.
