Features:
Mother Earth ;) pixel lighting, hi-res textures (adjustable model and texture quality).
Starry space (adjustable quality, time of the day affects brightness).
Your own custom backgrounds (up to 2-3 MB 1080p, could be transparent PNGs).
GPS tracking (when your GPS is online, the Earth could stop spinning and reflect your time of the day and location instead).
No ads or any such stuff.

System requirements:
A fair GPU ("fair" means "not the worst one").
A fair bit of memory - big textures come at a price!
CPU is used very little.
