That's nice, I hope you haven't done that manually.

Actually a fair bit is done manually, I have to find some pixel/gif art on the web, crop, desaturate, adjust light and contrast, and export the optimized image as ASCII .pgm file.
Then I just filter it on stdout with naive printfs.



/*

 * ============================================================

 *

 *       Filename:  pgm2char.c

 *          Usage:  cat file.pgm | ./pgm2char

 *

 *    Description:  Take an image file in PGM format as input

 *                  and output ``utf8 art'' graphics on stdout

 *                  █ U+2588 FULL BLOCK

 *                  ░ U+2591 LIGHT SHADE

 *                  ▒ U+2592 MEDIUM SHADE

 *                  ▓ U+2593 DARK SHADE

 *

 *       Compiler:  gcc

 *

 *         Author:  Anonymous

 *        Comment:  - Code looks very much like K&R Level 1,

 *                  and that's precisely what it was: 

 *                  some shit done as exercise

 *                  while reading Chapter I.

 *                  - Conversion to .pgm is done with Gimp,

 *                  Some other program might add comment lines

 *                  that will break execution.

 *                  You're on your own.

Now the same thing in one line of your favorite script language
