Through The Morning News
today I found a link to the blog Paleo-Future: A Look into the Future that Never Was
. Looks like a good source for pulp/retro-style sci-fi ideas for games. The particular post linked to in the title above has some promotional postcards from around 1900, made by a German chocolatier, that purport to depict life in the year 2000. The posts are labelled by decade, so you can browse for posts about views of the future from, say, the 1920s. Also, popular topics such as cities of the future, flying cars, robots, and the year 2000 are linked in the sidebar as well.
