.... just wanted to show there must be plenty of other applications
While vertical panoramas aren't as widely applicable as their horizontal counterparts, they do excel in some areas. Examples are any kind of running water, water falls, landscape details, light houses, forests, ..., in fact any situation in which subject relationships are manifested along the vertical not horizontal axis.
Composing the image in the narrow vertical format is more challenging, though. It frequently feels 'cramped' often in an uncomfortable manner. A quick survey showed at most 5% of my panoramic pictures are in the vertical direction.
