- For the creative component, I've change the background of the cube, but that
will affect how the planet picture look on the third sphere, so I edited it to
remove the cosmo-like edges.
- I've also added an orbiting earth and moon system that I've made from scratch.
The mapping texture(i.e., the bump and satellite world map) are found on Google
