I love equinox engine. I know it's maybe too "candy-like" but there are this things you can do with it in just 5 minutes: notice my transparent menu with white line around it ( i've tried to make it as close to Danrabbit's mockup as possible). And equinox glassy look is so awesome - of course you can make the same thing with murrine, but you'll have to spend an hour playing with gradients and lightboarders.
