There's no particular obstacles, except that

1) it takes a lot longer to make 10000 images than 100 images
    (100 times longer).

2) binocular vision and head motion parallax is usually left-to-right,
   so if you're going to go in only one direction, vertical strips
   are more important than horizontal strips.
