Why don't we have HD video of Earth rotating in space?

Why don't we have HD video of Earth rotating in space? You know, relatively close-up, as if the Enterprise had just dropped out of warp and the planet was being majestically introduced to the cinema audience. An extended, multiple pass/rotation exposure, so that it could be watched by appreciative viewers wanting to get a bit of perspective/peace. I imagine I would sit and gaze at this for extended periods. What are the technical limitations which have prevented this?

What's the name of this paradox?

I have vague recollections of someone telling me of a paradox many moons ago, it went thusly: There's no point in launching a spaceship on a deep space mission, because as technology advances so rapidly (e.g. Moore's law) that any ship you build in the future will be faster/more efficient and hence overtake any craft that you launch now, inferring that one should always put off launching a deep space mission. The same person told me it was called 'Clarke's Paradox' (I think?) but I can't find any reference to it, save Clarke's Laws (i.e. "Any technology sufficiently advanced will be indistinguishable from magic" etc). Can anyone help put a name to this paradox?

Would an alien radio pick up a cacophony or a damp fizzle?

If an alien located on a planet 100 light years from here was to switch on a big, multi-frequency radio receiver, and record all the noises coming from outer space for the next hundred years, on all frequencies, how many soap operas, advertisements and new broadcasts would they pick up from Earth? Would a mass-market radio, similar to our Earthly equivalents, pick up anything? Over time, as the number of Earth transmissions increases exponentially, would the alien pick up a cacophony or a damp fizzle? [more inside]
