Do you enjoy the beautiful dark menu bar on your iPhone or iPad? Thanks to a tiny free software called MenuBarFilter you can easily turn your Mac OS X menu bar into a dark, iOS-Like one.
While this is not the only way to get a dark menu bar for Mac OS X (you can find another workaround in this GeekTool Tutorial), the good point about this Nocturne based software is that with a single click it inverts the colors of menu bar and the including widget icons to give a shiny look to your desktop. There are currently some minor issues with this software which hopefully should be solved with a new update; for example if you are running Mac OS X Lion, it might not always work perfectly in full screen apps. Also there is no way to quit the software rather than going to Activity Monitor and manually quit it from there.
