The cultural significance of the propeller beanies in America, I told the translator that it would be best just to say. This technique requires you to be technically proficient.
Propeller Beanies
Putting On Your Thinking Cap
To represent a hero with an antigravity device, someone decided they should put a propeller on hats, and then quickly someone put one together from scraps of plastic he had lying around his room. The show in turn led inevitably to merchandising, and thus a cultural phenomenon was born.
That is the sense in which I've always known the propeller beanie: a representation of the nerdy programmer. I signed on as a tester for one of their products, and dutifully found and reported as many bugs as I could.
There being no drawings of the propeller beanies, I believe that he did in fact invent it. Although the propeller beanie appeared in comics for years afterward, the fad itself soon faded, and any child over a certain age was considered socially unsophisticated.
The classic propeller beanie is brimless and multicolored, typically with alternating wedges of yellow and red. Some modern designs add a brim, effectively making it into baseball caps with a propeller. You can even find motorized propeller beanies. What you cannot find, of course, is a propeller beanie with enough lift to fly off your head.
