Way way back (this would be when we lived in Cork I think, which makes it when I was fourteen or fifteen) I had a game for one of my computers.  It was about keeping a ball up in the air and getting points for the most amount of kicks you could make. Someone has re-created it with a more modern slant and James linked to it recently.  Check it out for some time-consuming fun!
