Ah, ok.  That makes sense then.  We should figure out the camera device
and if that's not actually there, do the fallback.  Ideally this would
work with any random v4l2 camera too, not just the one on the laptop.

Right.  We should just stick a random picture on.  How about Kiu's?

Because when on the laptops, there will be a camera that we can depend
on by definition.  I'd guess that we just want to use Kiu's picture from
way back and put that in the homedir or something so that at least
theres something you can pick.
