You and I are on the same page, I love your idea too. This is my very first project, I'm entirely new to coding, but hopefully eventually I can extend Hyperlax to what you're talking about. Appreciate you checking it out!
Last christmas in SF I wanted to create a "winter vibe" as we were celebrating with the family, and I was looking for videos showing cozy snowfall and winter landscapes. It was surprisingly hard to find something really good. I think it'd be cool if you could select what kind of "window" you want and had a few presets like "Tropical", "Winter landscape", etc.
I personally found the mix of soothing slow music and hyper lapse videos to not be relaxing, I think I'd prefer if the videos were running at normal speed or maybe even in slow motion depending on the video.
