Here's a weird thing about rock & roll and science fiction: The costumes are interchangeable. The Science Fiction Museum in Seattle is located alongside the Experience Music Project, and in a hall between the two there's a collection of costumes from Kiss, Devo, Dark Star, Blade Runner, and dozens of other fantasy worlds. Without a scorecard, I'd bet most people would have a hard time identifying which costumes are from rock and which are from sci-fi.
Here's another thing: Blogging might be this generation's science fiction. Before the Internet, people used the platform of science fiction to invent worlds, and write stories about them to explore radical ideas. Many were happy if they found just a few people to read their work and take them seriously, according to an exhibit in the first hall of the SFM. Sound familiar?
Anyway, if you are in Seattle and have even a nanogram of geek blood in you, visit the SFM. It's small as museums go but it's lovingly and thoughtfully put together, and sports Disney-level production values. There are lots of cool artifacts there (Captain Kirk's chair, for instance), as well as great trivia. For example, I learned that both Robby the Robot (from Forbidden Planet) and Robot (from Lost in Space) were designed by the same person, Robert Kinoshita (which might explain why Robby appeared in two Lost in Space episodes).
