this is the first time I participate here! I wish all participants «lots of luck» and look forward to seeing many cool projects (the first impressions are already fascinating!)! I know, I have no chance to win, but I just have fun to work in 3D.
my idea «Helix» wants to show how the world is still burning after the last war (. . . and will continue to burn for a very long time). the surviving population was able to adapt to this situation, constructing a huge "helix belt" around the earth's surface, and transforming the extreme heat from the globe as energy for their systems . . .
first sketch follows . . . keep on burning!
