Theme creation advice for dialer

[suavegarve]

I want to create a theme, mainly to darken the dialer. I want to create an effect that is the same as the attached screenshot which is the incall screen.

Does anyone know if this has already been achieved?

Does anyone know what effect this is?

Thanks in advance.

The effect you can see is a radial blur centered around the contact photo on top of a picture. I dont know that someone did this but u could just do it urself.
