The folks working on the proposed International Linear Collider have created a one-minute animation that flies you through its 30-kilometer-long tunnel. It has no sound, but the visuals speak for themselves: Electrons and positrons are generated on opposite arms of the collider, circle in opposite directions in a damping ring, fly out to the ends of the machine and jet back into the middle, where they collide. For more details about the humongous project -- which is scheduled to present a progress report at the International Conference on High Energy Physics on Saturday -- go here.
