Yeah I had a thought that using such a gigantic screen would dwarf any texture pattern seen in people's previous attempts. I would be curious to see a video which continually shrinks the lens image circle used until the texture became noticeable...

Those were my thoughts as well. Given that ProfHankD's 4x5" pinhole version of this linked below and my 6x9cm version of this both had visible texture issues, going that small is maybe not looking promising.

But maybe Matt's choice of diffusion material was also a significant step up. When he makes the parts list available I'd at least like to get my hands on some of it and compare it to various grits of ground glass (or ground acrylic).

I understand he didn't use any grit or diffusion material. He uses a 100% transparent glass (policarbonate) and two fine fresnels one to make the rays parallel, the other to converge light in the area of the camera lens. Maybe I got your comment wrong. He goes to say, with the diffuse screen, the light is too low and the patter too noticeable.
