Bah, the actual pic included in the pic is rectangle, fit for widescreens and even maybe cellphone screens.

Included in the .zip* sorry.

How did you get the blur effect after the initial render, and how did you get the separate emission planes to mix colors instead of showing the background? :)

Oh, i didn't exactly use a "blur" effect such as a Blur node in the compositing window, instead i used a very strong Depth Of Field focused on the cut out plane in front of the camera (which is black), this produces a blurry effect with everything behind that plane blurred out and sort of "blending in" to each other.
