Trekbbs has a monthly art contest. For May 2016, the theme is flags...especially ones that were NOT seen in Star Trek at all.
My entry is for May 2016 is Mudd's Planet.... (the episode where interstellar con man Harry Mudd had a planet of androids)
I wanted it animated, because without 20th century budget and technological restraints, flags should be able to change color
And with Harry Mudd, his stuff would be gawdy...and of course about him !
