Apple is moving away from the traditional look of OS X. In iTunes 7, I noticed a whole new look with different graphite scroll bars, smooth header that fit seamlessly into the interface, and new sleek buttons. This means Apple is changing Aqua, the theme Apple uses in OS X. Aqua is the look and feel of a Mac. In OS X Leopard, Apple will be performing an overhaul on Aqua, changing the brushed metal to a smoother interface.

So now I have to wait until Leopard to make my Mac look cool?

Wrong. UNO is a freeware application for OS X Tiger and requires iTunes 7. UNO unifies all my applications to follow a certain Aqua look. So, instead of all my applications looking a tad different, now everything is similar and sweet. Mozilla now looks like Camino on my MacBook Pro. Mozilla was bothering me the most, because I frequently have iTunes and Mozilla open simultaneously. Now they look like they belong together.
