What's the name of that game...(See Description)

You know, the one where they have these balls bouncing frictionless around the screen, and you make a wall that cuts it into a section, but if a ball hits you while you’re doing it you lose a life? Etc? Like this game, but the original:http://www.gamesolo.com/games/pacxon%5B1%5D.swf

For the life of me I can’t remember the name.
