Someone has graded the world's flags based on their aesthetic qualities. Here is the full alphabetical list of flags and their ratings. Flags get marked down for having the name or any other kind of writing, a map, or representational art, too many stars, "eyewatering" or nauseating color combinations, and lack of originality.
Some sample remarks:
Turkmenistan: Flag actually includes a Persian (sorry, Turkmen) carpet. Only flag to both make eyes water and induce vomiting.Mozambique: Automatic weapons on a flag are especially bad. Appears to have been designed by a committee all of whom had stupid ideas for pictures of extra things to put on the flag.
