The challenge is actually to extract five kilograms (=11lbs.), and that's a measure of mass, regardless of gravity.
Pounds, on the other hand, is a unit of force not mass - even though it's often confused as one.
In the imperial system the analog to the kilogram is the slug, defined as:
the mass of a free body which if acted upon by a force of 1 pound would experience an acceleration of 1 foot per square second; thus approximately 32.16 pounds. http://roland.lerc.nasa.gov/~dglover/dictionary/s. html>
To answer your question: It's 5 kilograms, and that's anywhere. (Not concerning relativistic issues:)
G forces are related to acceleration which is changeg velocity over time - so if you're staying at the speed of light there's zero acceleration.
On the other hand, we're going from zero to the speed of light, which does involve a significant ammount of effort.
Also consider that this simulation essentially only captures the Lorentz contractions at certain speeds. That means that points perpendicular to the direction of motion are lorentz contracted/expanded. That's why you're getting a fish eye effect that diminishes towards the middle of the video and increases toward the outside.
However the simlution is thin on what actually goes on:
-No red/blueshifting: since points are contracting so are observed EM wavelengths, and as a result are color shifted (across the whole spectrum, including IR and UV.) -Points in the movie would be seen in different times (although you wouldn't notice this since the world is static/)
Here you make a Newtonian assumption - velocities in relativity cannot be added so simply. As someone posted before, velocities have to be added only with the help of the Gamma factor, which would basically adjust your answer such that it remained under 100%. It's still impossible;)
I'm not sure if Moodlogic (http://www.moodlogic.com) runs on the Mac, but it will check your MP3 library with its own user-supported (and extensive) song database, and then rename and organize into folders your MP3's.
