How to make a desktop look like the ones in movies?

[Harsky]

A strange question but in a lot of recent movies (can't think of one off the top of my head) they almost never really show a stock PC operating system and it goes for a super fancy interface. I know that it's something created by the movie's FX department but does anyone know of any downloads that can make a normal Windows operating system look fancy and impressive? Almost, "LOL HAXXOR L33T" or the, "JUST GIMME 10 SECONDS AND I CAN HACK THE MAINFRAME FIREWALL".

For the most part it is a trademark/rights thing. Depravo gave the sensible answer, however I reckon the following is relevant too

You should look into rainmeter, it's very likely that someone has done a cheesy hacker skin. I mostly use rainmeter to monitor a few things and organize my desktop, but sky is the limit.

You have to manually piece together the individual elements but it looks pretty cool
