Proof-Of-Concept technique using Processing and technical ingenuity.
Seeing these examples reminded us of another “classic” method of making halftones: ASCII art. In what follows, we walk through the process of using making CNC halftones for engraving or carving from both vintage and automatically generated ASCII art.
Seldom seen nowadays, ASCII art is a computer graphics technique where grayscale photos or artwork are represented by keyboard characters on a regularly spaced grid. And while it does show up occasionally in the history of computer graphics, it is perhaps more important as a cultural artifact of the BBS era of computer networking.
While making ASCII art was once a painstaking process of hand creation— a true art —much of what is called “ASCII art” these days is automatically generated.
