Since your wall has been decidedly barren after the Great Quake of 3/5/12 totally broke your framed Willow movie poster, get awesome hangings from the Fantastic Four-person team (Programmer! Marketer! Laser Cutter!... Oboist?) at Woodcut Maps. This SF-based site creates inlaid woodcut recreations of any part of any city -- you just zoom into an area you like on a Google Map, select dimensions for your hangable, and choose what types of wood you desire, though "morning", like always, never gets used. Here're some attractive 'sterpiece suggestions that'll work on just about any wall, for just about any reason like:
Prettying-Up Your Apartment: This beautiful rendering of Golden Gate Park made from Macassar ebony, maple, and padauk's so detailed you can even make out the tops of the Cal Academy of Sciences and Museum of Fine Art, which's exactly what people are going to say when they see this in your pad.
Ironic Quinceanera Party in the Mission Gift: Immortalize your extremely skinny-jean'd friend's love of all things late-night-burrito via this cut of their neighborhood with a maple and walnut rendering of Dolores Park and the streets done in mahogany, which, oddly enough, kinda smells like Sex Panther.
Making Your Office Slightly More Bearable Because this thing'll totally complement your tan pleated chinos, topically decorate your place of work with a map of the place half the city seems to work, using delicately inlaid maple, padauk, and walnut, aka what you'll resort to in the mornings now that your walls are decorated so sexily.
