A screen shot was taken of a portion of Color Expansions' source code. The code fragment shown is from the section which grows patterns. (This code is in M680x0 Assembler and will run on Macintosh and Power Macintosh computers.) A pattern was then opened and grown within the source code picture, using "Mouse Start", a function which enables the designer to indicate a specific location within the Image Array where the pattern is to start growing, using the mouse. The pattern grew around the code within the white area. After the pattern was finished, the code text was thickened with green to enhance visibility.
