Applying a Cystallized/Mozaic Photoshop type effect to the camera

Hi,

I’m trying to create a image effect like this one: http://homes.cs.washington.edu/~edzhang/graphics/output/globos_Mosaic.67.jpg

I guess I could apply it to a texture/object or to a camera.

Any tips?

Thanks!

Texture object is a good options as it covers any active camera, and will allow you to adjust any alpha or color params.
