How do I change the menubar transparency in Lion? So I love the login screen in OS X lion, and I want to make my desktop look like that. I found the background image they use, but now I want to make my menu bar completely transparent like it is in the login screen. 

I've tried the "translucent menu bar" option in system preferences, but thats not the same at all. I googled quite a bit about this, but I can't find anything. Any ideas?
You would most likely need to use a translucent/transparent background image to accomplish what you're asking. If you know how to make an image 90% transparent then you should be able to experiment and to come up with something similar. Tweaking the UI is art in many ways, however, it's not necessarily a function of the interface creating the effect; the elements that compose it (background color, wallpaper, dock and icons) play a key role.

System Preferences > Desktop &amp; Screen Saver > Translucent menu bar




One app that I've used to achieve a similar effect is called Nocturne. I'm unsure of it's compatibility with Lion though.
