Center Blur

I'm in need of a shader that basically has the opposite effect of the vignette filter, where it blurs/darkens the center of the camera view and becomes clear at the edges of the frame. I've found a radialblur script in the Effects package, but I don't know how to attach it to the camera.

I've found some scripts that describe how to write and apply a radial blur effect, but the scripts throw some errors for me that don't seem to make much sense (it says there is an unexpected [ at line 35, when there is no [ at line 35 to begin with). http://forum.unity3d.com/threads/radial-blur.31970/

If anyone can shed some light on my struggle I'd be super grateful!

Thanks,

ok....got the radial blur script to work by changing how the samples array was declared, but unfortunately it doesn't do what I had hoped, so back to square 1 of looking for a "Center blur" shader.
