it all started when i found out that the cross of St. Patrick flag incorporated into the UK flag looks a lot like the Polish flag.
so i extracted it from the UK flag to make a flag for Poles in UK.
then i've noticed that it also resembles the flag of Chechnya. [there are some Chechen immigrant in Poland.]
so i made the background green, leaving the triangle blue.
then i found that it looks like the triangle of the flag of Czechoslovakia, and gave up any tries to make the meaning of this combo-flag coherent.
