Macroblock Study 5
The image data for what started as a white 8x8 pixel JPG file was repeatedly manipulated to produce the individual frames in this animation.  8x8 pixels is the smallest block size in the JPG compression format.
Same method as Study 3 but using a different sub-sampling method.
…I promise I’m done with JPG macroblocks for now…

Macroblock Study 6

Interesting things (faces?) found after databending Post number 38, replacing all “a” characters with “>” and then opening it in GIMP.

What would be great is to find the code/equations used to represent these in the JPEG format.

Macroblock Study 2 (8x8 pixel selections) 

A study of macroblock artifacts induced by selectively replacing characters in JPEG files.

The source image for these artifacts started as a 1200x1200px white JPG.  After 10 steps of replacing characters, various micro compositions are selected, highlighting macroblock artifacts.
