Other puzzles in the level required us to use the ASHPD's secondary feature, which allows you to carry small objects like boxes. In one instance we needed to create a portal on the ceiling- above a panel that needed to be depressed- and one on the floor nearby. We then picked up and dropped a small crate into the portal at our feet and watched as it fell through the ceiling across the room onto the panel ahead, allowing us to proceed.
Expect Portal to start messing with your mind later this fall. But even if you're not intrigued this futuristic head trip, you might want to consider letting Portal in your hard drive regardless, as it'll come bundled with Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, and Team Fortress 2 under the title Orange Box.
