I recently took a class in neon art, and made this design which I just hung in my hangar. Being an engineer and not an artist, I'm pretty proud of it! It doesn't show up well in photos, but the propeller is a krypton-filled tube with a "beading" transformer that makes it look like it's moving (and yes, it's "rotating" the correct way! )
