"Great art"? Depends largely on the person viewing it, but I think it also has to challenge our perceptions in some way. A photo-realistic work isn't necessarily great just because it displays a high level of technical skill. There has to be something else -- the perspective, the subject, the materials used -- that creates a feeling of strangeness, of seeing something new and different.
I'm primarily a fan of modern art and architecture. Favourites are M.C. Escher, Lawren Harris, Piet Mondrian, and Gustav Klimt.
