Apple's Mac OS X
Apple has been using a big "X", the Roman numeral for 10, as the logo for its Mac OS X operating system since 2001. The X looks like it's made of steel, in keeping with Apple's stark, minimalist aesthetic. The latest packaging, for Leopard version 10.5, evokes the mysterious monolith and space voyage of Stanley Kubrick's "2001: A Space Odyssey", a movie that has also influenced Apple's hardware design and product names ("Open the pod bay doors, HAL.")
The logo most likely to: convince you that you're cooler than you really are.
