Drawing with jpg macroblocks

This was just a one of test in which I tried to use pre-existing jpg image's macro-blocks to do a self protrait with. Without getting technical, I could say that it is like drawing with pre-existing compression artifacts and moving them around until one image becomes another. That doesn't really explain it but I am too tired to type 20 paragraphs.

So this is how JPG compression works!

I have so much more respect for the computer after trying to draw like one. Understanding how simple things like compressing a JPG image require some pretty creative constructions has completely changed my view of the dichotomy between the analog and the digital.
