What iPhone app makes your picture like this?

I see a lot of people on facebook using this for their profile pic.i've always wondered what app they used.

it basically makes your whole picture a little blueish, and on the side, there's a smudge of red. It looks really cool. Does anyone know which app it is? :P thanks!

What you may be asking about is a 3D technique called Anaglyph

It is shot using two identical cameras and lenses, one with a cyan filter and the other with a red filter.
