Creeping Thyme is a good solution. It tolerates moderate treading (i.e. a family walking on it on occassion or kids playing but not vehicles or wheeled stuff), it uses practically no water, it grows slowly so it rarely needs to be cut, and it only grows a few inches in height at most so often it doesn't need to be mowed at all, and blooms in the spring with tons of tiny little flowers spotted all over your lawn. It comes in a handful of varieties that all grow between 2-6 inches in height and have a variety of textures or flower colors.
