When the C64 was launched in 1982, it was a powerful home computer for creating computers graphics. Contemporary hardware is an interesting place to re-imagine the 10 PRINT algorithm because it has changed substantially from its predecessors. For this exploration into re-imaging 10 PRINT, we used Processing, a programming system first designed in 2001. It is built on top of Java, one of the dominant modern programming languages, but Processing exists to create graphics and simplifies some of Java's native syntax. Introduced in 1995, JAVA is most similar to C++, which itself is from 1983. C++ is an object-oriented programming language built on top of C, a procedural language originally from the early 1970s.

Processing is a system for creating interactive sketches, one which has its own keywords and syntax that are used to define programs, as is done in BASIC. Unlike BASIC, which was originally developed for working with numbers and text, Processing was designed for creating graphics. For example, while a simple BASIC program writes some text to the screen with <tt>10 PRINT "HELLO WORLD"</tt>, a simple Processing program draws a square to the screen with <tt>rect(20, 30, 80, 60);</tt>. This one-line Processing program draws rectangle with its upper-left corner at coordinate (20,30) and with a width of 80 pixels and height of 60 pixels. At its core, Processing is an image-making programming language that builds on knowledge of geometry, photography, typography, animation, and interaction. Because Processing is situated between programming and the visual arts, it's a bridge between two professional cultures. Programmers who approach Processing from their background are encouraged to learn more about making sophisticated visual images and from the other side, visual artists learn the fundamentals of procedural literacy.

Like BASIC, Processing defines programs through is mixture of words, numbers, and symbols. Unlike BASIC, which was originally developed for working with numbers and text, Processing was designed for creating graphics. For example, while a simple BASIC program writes some text to the screen with <tt>10 PRINT "HELLO WORLD"</tt>, a simple Processing program draws a square to the screen with <tt>rect(20, 30, 80, 60);</tt>.

Because Processing is situated between programming and the visual arts, it's a bridge between two professional cultures. Programmers who approach Processing from their background are encouraged to learn more about making sophisticated visual images and from the other side, visual artists learn the fundamentals of procedural literacy.

The first Processing version of 10 PRINT was written to take advantage of the increased resolution of contemporary screens. It does this by making the thickness and ends of the lines into variables that can be changed while the program runs. The lines of the maze can range from 0.5- to 10-pixels wide, and the lines can terminate with a rounded or square end. Like 10 PRINT, this Processing version of 10 PRINT maintains the grid of lines at 40 x 25 units, but, unlike 10 PRINT, it doesn't add each grid unit in sequence from left to right and top to bottom. In the new high-resolution version, the entire maze is refreshed at once. Using the default Processing colors to create white lines and a black background confers a mood similar to that of the original lower-contrast blues of the C64 (See Figures ?? to ??).
