Take any ball game: Football, Cricket, Rugby, Hockey, Basketball.......
Night games are usually played under multi-billion wattages of floodlights. This means that there is nothing different in the sport except for the time of the day.
I suggest a radical change in all ball sports. They should be played in total darkness; giving away only a few clues of the location and position of the players and the ball.
Players should wear glowing strips on their clothes and their extremities. For example, they can have a glowing headband, glowing motorcycle-gloves-shaped gloves, one glowing strip at the waist, glowing kneepads and elbowpads and glowing shoes.
The ball should have a glowing strip on any two perpendicular 'equators'. Teams can harness colour coordination and refs can wear all-glow outfits.
This way, Night Games will never be the same as Day Games, since they will demand greater levels of anticipation from players while keeping the required skill level more or less the same.
// Addendum:
The target zones in each sport also need to be glow-lighted; eg: goalposts and penalty boxes in football, backboards in b-ball, stumps and creases in cricket, whatever they use in all the other sports.-- joker_of_the_deck, May 28 2003 Sounds like it'd be kinda fun, but with a high potential for injury. I guess there already is a high risk for most sports, though.-- goober, May 28 2003 Do they get headlights on their motorbikes? It would be rather difficult to navigate the track otherwise.-- silverstormer, May 28 2003 Great idea. I once juggled with glowing balls in the dark, it was surreal.-- OnionBread, May 28 2003 Yet another idea done once then reborn.-- phoenix, May 28 2003 <tangent>A fun thing to do in the dark, if you happen to have a strobe light handy, is to try walking directly toward a wall in a room lit only by a flashing strobe. It turns out your depth perception is affected by light intensity, so you end up thinking the wall is far closer than it really is and stop several feet away from it.</tangent>-- krelnik, May 28 2003 Yea [Tom] thats a better idea... definitely more viable! I'll give you a [+]!!-- joker_of_the_deck, May 28 2003 ...or you could go edit the idea whilst giving credit to Tom.-- goober, May 28 2003 random, halfbakery
