I have an iced tea maker...you don't necessarily have to make tea in it...sometimes i put slices of ginger in the filter or mint leaves and then you can add a little lemon or lime juice after it brews for flavor and a sweetener like stevia, agave or Splenda. Fresh and yummy!
Of course, you can always make various teas also-green, black, white, and red. Go crazy! One of my favorites is Good Earth sweet n spicy tea because you do not have to sweeten it at all and it's still delicious.
