Sometime in the future, a large spacecraft is taking off from Earths orbit, filled with passengers on a long journey to somewhere else in the Solar System. This may be the first large colony to permanently settle another world.
The background is a classic photo of the Earth from space, with the sun setting over the Pacific Ocean, taken from the International Space Station on July 21, 2003. I mapped the photo on a curved plane and replaced the optical flare from the sun with a digital flare to be able to create some motion. The original photo can be seen here
The spacecraft is a digital 3D model, obviously.
