Laser Images used to use perforated aluminum dipped in lacquer as standoffs with a "granite" art glass disk or as a disk with some other lumia disk for a nice effect. You dip the perforated part in the lacquer and spin it until the lacquer sets up. The result is an array of little negative lenses.

Mesh disks, stainless steel, look up Ronchi Ruling and find a diffraction calculator on-line.

There is a limit on how fine you can go, but can be um, interesting at short range.

Two plastic sheet gratings crossed to each other on motors is the transmission version of lissajous patterns.

... some years ago I was developing applications with/for paste-dispensers for high viscous glues and pastes.

With this you can "print" all sorts and sizes of lenses or "regular surfaces" ... now image, you'll print some of this with the previously mentioned "Acrifix 192", what will give perfect transparent PMMA structures and surfaces

Attached images from a test pattern and a "tactile image", printed with blue UV-cured glue (would be the same structure with the transparent PMMA-glue ... and a video showing the process with a "braille-image" too:

Interesting - Thanks!
