Binary Visualization

Binary Visualization based on Christopher Domas talk: https://www.youtube.com/watch?v=4bM3Gut1hIk

Main Idea

• Scan the pairs of bytes of a file with a sliding window. (AA BB CC DD ... -> (AA, BB) (BB, CC) (CC, DD) ...);
• Interpret the pairs of bytes as coordinates on a 256x256 2D plain;
• Place a dot for each pair on the plain;
• The more frequent the dot, the brighter it is;
• Different patterns emerge depending on the type of the data of the file.
