Goalball will be one of the more interesting sports on display at the Paralympics. Here's are the rules according to Wikipedia:
Participants compete in teams of three, and try to throw a ball that has bells embedded in it into the opponents' goal. Teams alternate throwing or rolling the ball from one end of the playing area to the other, and players remain in the area of their own goal in both defence and attack. Players must use the sound of the bell to judge the position and movement of the ball. Games consist of two 12 minute halves (formerly 10 minute halves). Blindfolds allow partially sighted players to compete on an equal footing with blind players
As far as I can tell, I don't think Ireland have a Goalball competing in the Paralympics. Photos of this strange and fascinating-looking photo below.
