Next time you want to check the score or team/player statistics, don't look at the scoreboard, look at the players' jerseys.
Australian researcher, Mitchell Page, came up with the concept of the TeamAwear jersey. Designed to light up whenever a player scores or incurs a foul, it also had an unexpected benefit on players' psyche when they tested the jersey out.
Personally I don't know if I want to see a bunch of players out on the court or field lit up like a Christmas tree.
