I don't like concrete - at least not the standard concrete slabs of last century. In a real estate ad I saw a patio taht I like. It may not be usable for a driveway though. Variations: there can be grass, thyme or gravel between the large pavers. The pavers can be flagstone or concrete.
I don't think the entire driveway should be paved. It might look better with driving strips from the public road till the central driveway/entryway.
Or perhaps more appropriate for a driveway there is this design (from http://www.inhabitat.com/2005/11/27/light-emitting-tiles/)
