As a side note, from the Archival records and articles in the UK, it is known that the Schools of Art of the time (1700s) took apprentices and trained them, in either the 'one-stroke' style required for decorating ...

The Children's Discovery System used a 16-by-48 matrix LCD screen [12] [13] and was powered by six size AA alkaline batteries. [14] The screen was much wider than it was tall, therefore only a grid of 8-by-2 text was possible, allowing for a maximum of 16 characters on-screen at any given moment.

A cel shader is often used to mimic the style of a comic book or cartoon and/or give the render a characteristic paper-like texture. [1]
An example of two kinds of shadings: Flat shading on the left and Phong shading on the right. Phong shading is an improvement on Gouraud shading, and was one of the first computer shading models developed after the basic flat shader, greatly enhancing the appearance of curved surfaces in renders.
There are various techniques of shading, including cross hatching, where perpendicular lines of varying closeness are drawn in a grid pattern to shade an area. The closer the lines are together, the darker the area appears. Likewise, the farther apart the lines are, the lighter the area appears. Powder shading is a sketching shading
Thayer's 1902 patent application. He failed to convince the US Navy.
