You guys are all wrong.

When I uber l33t haxor a computer it shows me nice 3 dimensional rectangles representing the file system (See Hackers)

Virii are cross platform and cross language. Why once I flew up to a big space ship where I used a floppy disk to infect an alien species computer system and stop them taking over the earth. The virus resulted in a nice 3d spinning skull effect on the aliens screens.

It also infected all the neighbouring space craft. (I think they were using wi-fi or bluetooth)
