2 was done by Quasimondo.
Sam Hocevar wrote img2twit,(3) which segments the image into square cells and tries to randomly assign points and colours to them until something is close.
And then Boojum wrote a nanocrunch.cpp, based on fractal compression which is 4.
compress an image so that it can be sent as a single tweet.
