Trex.swf

trex.swf is a screamer made by kebabfrites. When clicked on, it downloads a file called trex.swf. Once archived, a file called stream.mp3 is made. When opening this file, it plays the audio of a Tyrannosaurus Rex making a distorted, mechanical animal roar.

If opened on a SWF file player, however, a shaking picture of the dinosaur will appear as the file's visuals.
