The image contains inverted Morse code, meaning the white pixels are the signal and the black pixels are silence. This Morse code, when decoded, yields the clue phrase CAITSITH2 SAYS: USE RULE SEED 266! NUMBER OF DISTINCT PORT TYPES = ?.
The title of this puzzle is reminiscent of Morse-A-Maze, a module created by CaitSith2. When the manual is opened with the rule seed 266 as instructed, the solution word can be found associated with the instruction “Number of distinct port types”.
