If you are unfamiliar with this project, they are developing small pieces of scenery (usually revolving around helipads and heliports) that they then sell for cheap -- around £1.
All the money they make goes directly to the London Air Ambulance. After the release of their first project, Vanguard Heliport, the team is now releasing the Royal London Hospital.
So, folks, help these guys do some good. Grab the scenery and be sure that you are helping a great organization!
