He developed a small application that takes an image (jpeg, gif, or png) and converts it to a set of pixels, which can then be tweaked and skewed to his liking. The application exports the halftone image to a DXF file which can be fed into the CAD application that he uses to control his CNC machine. The CNC does the rest, using a v-shaped router bit to cut holes into his workpiece, generating a physical halftone picture from his digital image.
I wonder what kind of effect you would get by making some custom laminated material to then cut. Like a kind of homemade plywood with each layer dyed or stained different colors. Mind it would probably mess up the halftone effect though.
Nice and another good example of how old knowledge and techniques can have a second life. If you have access to graphics software you could try something I used years ago to create some signage. I processed the image in PhotoShop (halftone filter or saved as dithered BMP) then opened in Illustrator* and used the Live Trace option to convert to vector (Flash has a similar function). Then I had to open the vector file in Corel Draw to export as a DXF.(*actually I used Adobe Streamline to vectorize back in the day)
As VectorStyler was already mentioned (as a useful companion app), it is probably worth a note that it can be used both for creating many kinds of (at export time rasterized) artistic halftones and true halftones, by printing to PostScript files and then rendering to monochromes at desired resolution using e.g. GIMP:

Preserve: Retains the transfer functions that are traditionally used to compensate for dot gain or dot loss that may occur when an image is transferred to film. Dot gain occurs when the ink dots that make up a printed image are larger (for example, due to spreading on paper) than in the halftone screen; dot loss occurs when the dots print smaller. With this option, the transfer functions are kept as part of the file and are applied to the file when the file is output.
Preserve Halftone Information: Retains any halftone information in files. Halftone information consists of dots that control how much ink halftone devices deposit at a specific location on the paper. Varying the dot size and density creates the illusion of variations of gray or continuous color. For a CMYK image, four halftone screens are used, one for each ink that is used in the printing process.
In traditional print production, a halftone is produced by placing a halftone screen between a piece of film and the image, and then exposing the film. Electronic equivalents, such as in Adobe Photoshop, let users specify the halftone screen attributes before they produce the film or paper output. Halftone information is intended for use with a particular output device.
Dithering is analogous to the halftone technique used in printing. For this reason, the term dithering is sometimes used interchangeably with the term halftoning, particularly in association with digital printing. 2b1af7f3a8
