Every couple of years, someone on the internet demonstrates how they adjudicate screen-peeking. Two kids tape a Toy Story blanket to their TV, ensuring an airtight barrier between both halves of the CRT display. One player stands up in the middle of a Halo deathmatch, while his two friends are condemned to their own MacGyvered pods. Never again shall they be victimized by a dubious plasma grenade. Another group came up with the same mechanism. I imagine nothing feels worse to game with than a flap of cardboard resting on your head.
