Once there was a bored little Webdesigner.
One day he thought: “Wouldn’t it be nice to make a Flash version of the Portal end credits?”
No sooner said than done, he extracted the commands and the music from the game files itself, and wrote an interpreter for them in Flash.
My luck the Portal end credits are text based commandos and not a video, so i could take the commandos to reproduce the credits 100% identical in flash. You can even copy and paste the text.
