It’s probably the starcraft in Star Wars that have featured the most iconic and memorable design. The racing stripes on the wedge-shaped A-Wing starfighter always looked cool (like dogfighting in a Dodge Viper?) and the spindly angularity of the Nebulon-B escort frigate made it look like it was going to beat the crap out of you. I think that strong design helped Star Wars become what it did, as fans could have the familiarity of recognisable ships as they moved from watching the movies to playing the games.
Likewise, a simliar level of work went into much of the architecture. The Architects Journal have detailed how some creations have influenced real-life counterparts and sometimes vis-versa.
Bright Tree Village is an exemplar of sustainable, low-tech development. This Ewok settlement on the forest moon of Endor follows the traditional pattern: thatched-roof huts are arranged on the main branches of a tree around the chief’s hut on the trunk. Rated BREEAM Excellent, the development – by architect Wicket W Warrick – makes use of locally sourced materials, is carbon-neutral and far exceeds Endor’s notoriously strict building regulations.
