Behold: Facebook’s Secret Photo Sharing App
The app seems to be a combination of Instagram, Color, Path, and even Path’s new side project, With.

Also worth noting is that Instagram co-founder Kevin Systrom was once approached by Mark Zuckerberg about working at Facebook way back in 2004, after they caught wind of his first take on a photo sharing service. Systrom declined the invitation, and now Zuckerberg is a Instagram user (which also connects to Facebook).
