You know... Leo, Scorpio, Gemini and so on. Choose any ONE of the 12 Zodiac signs and build a moc incoorporating that ONE sign into it. (in case you haven't noticed, you're only allowed to choose ONE of the twelve signs). No size limits.
The Intergalactic United Nations organization (I.U.N.O.) provided life-sustaining resources to civilizations who had suffered from the raging war. Unfortunately, not all nations could distribute the supplies brought by the massive ships amongst themselves and resorted to primal and barbaric inner-atmosphere war.
The I.U.N.O received donations from many of the wealthier and more advanced civilizations. Amongst these were the Aquarians. They became known as the life-givers of the galaxy, remaining always a neutral force and aiding all those planets that needed life-resources.
I couldn't decide wether to try SHIPtember or the M.O. so I made a ship (instead of SHIP) with the symbol of aquarius emblazoned on the side and entered the Olympics. Thanks for making an awesome category, judges. It is specific, yet very open-ended in terms of interpretation.
