Half-Life 2 Panoramics
rgovostes writes "VRMag, an online panoramic magazine, has QuickTime VR scenes from Half-Life 2. The corresponding article, Half Life 2: A Panoramic Approach, explains how the images were made and relates photographic elements with the game's rendering engine."
Apparently nobody ever tried to tell a story in a game before 1998!
The funny part is that in order to view these things smoothly, you almost need a system powerful enough to play HL2 anyway.
