Chrome flaps

On of Germany’s most popular tech bloggers (@Caschy) recently published a notice about Google Chrome 9 final on his blog – and attached the following Chrome logo to the news…

Google Chrome 9 final Portable Google Chrome 9

..which I’ve marked with red arrows, because I’d like to know from YOU, dear reader, if you know what these sort of landing gear flaps on the logo are all about (?).

Someone on Caschy’s blog suggested it is part of the Jefferies-tubes, someone else wrote they are flaps for a microphone and a camera.

Seriously, do you know why they’re part of the Chrome logo and what’s the story behind them?
