I'm creating a new map for the game Half-Life, modeled after the TV station where I work. If you're interested in the process to build it, here's a screenshot. You'll notice I've also got iTunes running. That REALLY helps the process..
If anyone has the game and would like to play my map, visit me and my buddy Iceage's Half-Life mini-site. That's where we post our progress on different HL related stuff.
