That is not the Flat UI icon.

I remember it distinctly from launch, the cogs were more inside the circle and in a different orientation: http://venturebeat.files.wordpress.com/2013/03/screen-shot-2...

The three icons removed were the cog, the map, and the twitter face.

Edit: Here is a comparison image from further down the page: http://imgur.com/IH1osAD

Anyone else troubled by the idea of three interlocking cogs? I mean, it's an icon meaning deadlock, right?

That would make sense if all three cogs were interlocked but they are not. The top two cogs are not close enough to each other.

Yes! It's something that makes me twitch each time I see it.

I know other people have discussed it, but my search engine skills are too weak to find anything at the moment.

KDE has been using similar gear iconography for at least a dozen years. http://www.google.com/search?q=kde+gears+icon

Is this the best example of the "infringement"? If that's the best they got than Layer Vault are looking pretty foolish (insecure, full of themselves, etc). What a joke.
