CORK: Diffuse or Absorb?

I bought these cork bath mats a while ago. I use them over a window just to the right of my speaker and duplicate this on the left side. I just bought a Vicoustic diffusion panel, the Multi-fusor wood 36, and mounted it in back center of my speakers. I very much like what diffusion does in my room, and want to do ad more. So back to the original question.... Does anyone know if Cork absorbs or diffuses?

It seems to me that cork would absorb sound. But, it also makes sense that if it were arrayed in a way other than a flat sheet (i.e. corrugated or misshapen in some fashion, it would diffuse sound very well.
