Ido

Ido is a European auxiliary language based on Esperanto. 
The flag is a blue background with a six-pointed star, with three of the star's points reduced, the longer alternating with the shorter, one longer pointing upwards. It's sometimes said that the six pointed star stands for an "upgrade" of Esperanto's five pointed star.
