Well, I don't really understand technical music stuff, but I do like looking at graphs and charts, so thanks dude. And I know about geology/gegraphy and all of that stuff.
I also have a top three of graphs, not surprisingly, and this beauty, the Hjulstrom Curve, is my favourite. It relates, with quite stunning beauty, the relationship between water velocity, sediment size and erosion/transportation/deposition.
Your first picture looks like a nice satellite image of a river winding through a semi-developed area. Nice. Sorry to hijack yr thread with some earth science. I just wanted to share the Hjulstrom Curve.
