Thanks for sharing these :-)
The NYC one is very clever (I read the explanation underneath), but I found myself feeling slightly overloaded, partly because there's so much detail in each layer and partly because of the music. About halfway in, I started seeking some sort of relief, muting the sound and preferring to look at the water and the sky. Watching the sky is something I enjoy every day. I like trees too; they make me feel calm, somehow.
In contrast, I liked everything about the droplets. The music is slower and more delicate, and I love the moments of collision where jellyfish-type shapes are created. My breathing slowed and my blood pressure decreased; by the end, I felt well rested, which was pleasant!
