Valve Software is working on a second helping of downloadable content for Portal 2, and they've revealed that it will include an in-game map editor. It's planned for early next year, and it will allow players to create both single-player and co-op maps. The maps can be shared with others, and there will be a system to view and vote on other people's maps. In other Portal-related news, a reader sent in a video of his efforts to get GLaDOS running on his home computer. He writes, "I used Microsoft's Kinect technology as the platform and sound files from my copy of Portal 2 to create my own GLaDOS. My plan is to make the source code (but not the audio files) open source once it gets farther along. The technology has already been useful to my parents in helping them more easily navigate a computer."
