This is a shot of the American Flag I constructed over my base. The light colored vertical line above it is somebody else mining beacon. I don't recall the dimensions, but you can get a feel for the scale from the size of the hill and the base. The top several stripes were in the clouds. The dark colored feature just below it was the platform I used to work from, and was later removed so that the flag was free floating above the base. I bred sheep specifically for red-white-blue-orange where the orange was for the edge "fringe" that on a real flag is "gold."
The second shot is my sheep pen from the reverse angel. Can't see the flag, but you can see the size of the base so that it gives a feel for scale, and you can see the mining beacon at the right of eh base.
It's not as extravagant as many projects I've seen from others, but for me was my first major project, and still one of my favorites.
