O'Neill Island 3 Colony v0.9 2010-04-10

A 50km long rotating space colony, designed to be placed at the five Earth/Moon Lagrange points.
...Unfortunately that turned out to be beyond my scenario-programming ability, so I've put five of them in wide orbits around the Earth and the Moon, to give about the same impression.
Perfect for adding a sense of advanced civilization to your scenarios, or giving yourself a destination beyond the ordinary station or base.  The source code is included in case anyone wants to improve or redesign it.
Many thanks to Ursus on Orbiter Forum for help with the C++ and getting the gravity drum to rotate.
<<UPDATE>>
 
Thanks to ajaja's wonderful and intuitive Lagrange MFD just made available on Orbit Hangar (http://www.orbithangar.com/searchid.php?ID=4582 ), the colonies are now in their proper positions. 
You should download this MFD A) because it's useful in general and B) while some playing with time acceleration shows the colonies will stay in position long enough for the purposes of a few flights around the Earth/Moon system, if they begin to drift, you can shift focus into them and use the "GO" button on the MFD to zap them back where they belong.  Thanks, ajaja! 
Happy flying!
