Instead of spectators sitting down and watching some football or soccer like game on tv, we could use the newly invented holotechnology to capture the game, and reporoduce it in 3-d, live, onto another field of the same size, perhaps in a different city. That way spectators could be 'in the game', whatching their sporting heros rush by them, as they watched the game, from the center of the game. Exciting? no?
