I'm not too sure this question is well-posed, there simply isn't an isometry of space that would take a trajectory traveling faster than the speed of light and make it inertial. As such we have no description of the laws of physics that someone would experience on such a trajectory. So how things like red/blue-shifting etc. would work out is simply not knowable.
Now if you were just wondering what you'd see if you simply changed position really quickly then you can just imagine putting lots of cameras in a long straight line and triggering them in turn to simulate a superluminal speed then you basically would just see the stars move more quickly than possible. You'd also see time progressing backwards on the stars that you are 'moving' away from and more quickly on the stars that you are 'approaching'.
So the stripy stars bit is not really that far off.

Or just watch Star Trek, as the iconic “moving through stars” happens throughout the series (mostly TOS, as others added different effects)
