When you know your mood but not what movie you want, a simple categorization system can assist your selection -- except for that dark day "Flicks for Kids" led you right to Boys Don't Cry. Now, get the same guidance for sweet inexpensive art, at The Untapped Source.
An e-gallery housing works from artists "who have yet to be fully recognized and exposed", UT peddles dirt-cheap prints ($15 to just-over-$100), all optimally sorted for your searching pleasure. Hit the "categories" tab and you'll get 35+ classifications, some of which swing accessible, like Still Life, Architectural (photos of crumbling castles, crazy staircases, etc), Natural World (landscapes, rock formations), and Artistic Nude (photos of naked chicks, paintings of naked chicks -- sorry, naked dudes). Slightly less real-gallery-tastic're Auto Portraits (supercar paintings, rotted-out abandoned truck photos), Sci-Fi (cyborg aliens, fearsome dark planets), and Sport: Dr. J/Sir Charles paintings, surfing/skateboarding photos, even bloodied MMA dudes -- allowing you to hash out "Is it real art?" and "Is it a real sport?" arguments all at once.
You can also browse by Traditional/Photo/digital, and once you find an artist you dig, you can easily ditch the categories and check just their work -- and you won't be as bummed as when Boys Don't Cry led you to Million Dollar Baby, where Hilary Swank was disappointingly unconvincing as a woman.
