Ever since trying out Google's photo sphere feature (yes, they weren't the first ones in the space - Microsoft and others actually beat them to market), I've been quite interested in the concept of 360° by 180° ways to explore places.
I've used the feature to document, especially, my hikes, and a trip to Peru (https://www.google.com/maps/views/profile/111004183840840391...). I've experimented with using my DSLR to do the same (https://www.google.com/maps/views/view/111004183840840391992... and https://www.google.com/maps/views/view/111004183840840391992...).
And, after all that, what would I love to be able to do? Take a video with a setup that is something like in the link and be able to put together a 360° by 180° video that would allow a viewer to follow along with me skiing down a slope in the not so snowy mountains of southern California, or enjoying a zip line through a cloud forest in Costa Rica, or descending on bike down a mountain road. Imagine being able to view such a video but being able to pan side to side, up and down, looking forward or backward - basically, allowing the viewer to pan to any angle at any point in time in the video.
I have to imagine this is not a novel idea, but I can't say I've seen any demos of such an experience. I'd love to see some if they exist.
Anyway, just some thoughts I had while enjoying the video in the link.
