The sweeping arches and jutting supports seemed to defy gravity and make customers feel as if they were next to, or inside of, a hovering spacecraft. Suddenly new buildings were sporting alien looking spires or floating parabolic rooftops. Even churches, especially Protestant, got into a (albeit subtle) futuristic mood resulting in some very ethereal houses of worship. And they were mostly made of clunky flagstone, concrete, and steel, mind you -- not the lightweight composite materials available today -- with lots of glass. This made the eerie floating effect of the designs seem all the more intriguing because of the contradicting heaviness of the materials. Designers had a lot of fun with lettering as well. Text hovered all over the signage, and resembled bubbles, stars, and other heavenly objects of our imagined birthright to the universe. Colors used were often the popular shades of the 50's -- mint green, melon, turquoise -- but when outer space was put into the mix, any bright neon colors on the background of dark blue space were appropriate.
Unfortunately most of these funky space-aged works of art have either been left to deteriorate on vacated lots, or are being systematically demolished, to be replaced by the bland imagination-less buildings (or the self-important gargantuas of New Las Vegas) currently popular today. Thankfully there are local organizations springing up to attempt to save these artifacts of the spirited era that conceived them, but many of the best have been lost. So go out and find some Googieness where you live, and take a few pictures just in case it won't be there very much longer.
A good book on Googie history:
