Basically, it shows off one of the most overlooked features of Transcendence, background plane.
Planets have random parallax planes due to use of TypCreate, and makes the game look way better.
It's very fun to have, and I really, really have to thank digdug for letting me use his planet graphics!

(technically, I stole this from Sandbox code so this also counts as a Sandbox teaser as well >.>)
