been looking up translations of "welcome" in various languages and matching that to the flags of various countries.

concentrated on the most English alphabet languages and the easiest flags (with no annoying logo components). Although I did generate a couple of cyrillic characters to make another one work.

also limited the options to countries which own their own language - ie no American or Australian flags included but the UK flag rather than literally the English flag.

Flagon says, roar! Croeso y Cymru!
