Jeremy Burge is the founder of the Emojipedia index, so naturally he'd be the man to discover this: Apple has designed a rather weird emoji, as yet unreleased, but tucked away in the developer preview of the forthcoming iOS 9.1 update.

Burge, Redditors and others are wondering just what the heck it means. To be clear, this is not an icon representing an app; it's an emoji meant to be placed into a conversation to communicate something. But what?
The consensus seems to be that it's an eyeball inside of a speech bubble. The expected jibes have surfaced—it refers to CBS, Sauron, the Illuminati, or the fact that the NSA is watching you, say the jokers—though more sober commenters speculate that it simply means "I see," as in "I see what you are saying." Others think it means "Bullseye," and still others wonder if "Apple might have some forthcoming feature for which this emoji is an indicator."
