For a fun Friday afternoon diversion, visit David Szondy's Tales of Future Past
, an archive of "future" visions of past eras, complete with vintage artwork and insightful commentary (much of it noting the practical reasons why these futures never came to pass). If you're wondering what happened to the flying car, robot servant, domed city or condo on Venus you were promised way back when, this is the place to look.
For those old enough to remember the '60s TV show Thunderbirds
, the site also contains some great images
