What's in the background?
It's the window view of the International Space Station (ISS), coming live from their embedded video camera via Ustream.
Not seeing it?
Either ISS is in the shadow of night (you can tell by this map), or they're adjusting camera. Be patient.
So what's my point?
If your screen is the window of ISS, then consider this greenish futuristic design as astronauts' control interface on that window. It is my belief that in the near future, interfaces will appear more and more on tangible surfaces, not screen-based devices.
