The "Carnivore Personal Edition Zero Client" (serial number RSG-CPE0C-1) was the first Carnivore Client. It was written in Perl by RSG and ran on the dumb terminal output of the first Carnivore Linux server—like a welcome screen. It was first ported to Visual Basic in 2001 so it could run as a screensaver on Windows machines. To make it web-accessible, Todd Holoubek ported it to Flash in December 2002. You can view it on the web (demo mode only), or download the files to run on your own LAN using CarnivorePE. Keep in mind that this is an emulation of the original work. The colors are derived from default ANSI colors. The font is a default terminal font. The column height and row width are also based on the terminal window. The audio is taken from the game Half-Life. The surveillance packets are simply printed to the screen left-to-right, top-to-bottom, in a pseudo random fashion. The piece is not interactive. Just let it run.
