I did a simple little project recently that creates a gif visualizing the bit patterns within a file.
The program takes as input a file name, and outputs a gif consisting of colored cells whose brightness is based on how frequently the corresponding bit pattern occurrs. The bit pattern for a cell is just that the top left cell is all 0s, the next is 01, then 10, 11, 100, etc.
The gif moves from showing 2-bit patterns, then 4, then 6, 8, 10, 12, 14, 16. Of course, powers of 2 are the most interesting because the data is laid out that way.
One interesting thing is that the brightness is actually the log of the frequency- small numbers, especially 0, occur so often that just using the occurances directly leads to a white pixel for 0, and dark pixels for the rest of the image.
Anyway, I just wanted to do a simple visual of bit data. Also, now I know how to create gifs with Rust, which is cool.
There are some examples in the repo from text data, which bunches up in the visual ascii range, and an exe which is more uniform. I also found that data files, like recorded CCSDS packets, produce nicer images then a corpus of english text, for example.
